III Before Installing
1) Safe, reliable operation of this boiler depends upon installation by a professional heating contractor in strict
accordance with this manual and the authority having jurisdiction.
• In the absence of an authority having jurisdiction, installation must be in accordance with this manual and
the National Fuel Gas Code, ANSI Z223.1. In Canada, installation must be in accordance with the
B149.1 Installation Code
• Where required by the authority having jurisdiction, this installation must conform to the Standard for
Controls and Safety Devices for Automatically Fired Boilers (ANSI/ASME CSD-1).
2) TRIUMPH boilers utilize aluminum heat exchangers constructed, tested, and stamped in accordance with
ASME Boiler and Pressure Vessel Code Case 2382. Some jurisdictions which require ASME boiler construc-
tion do not recognize this Code Case and may not approve the installation of an aluminum boiler. Consult the
authority having jurisdiction before installing this boiler.
3) Read Section VI to verify that the maximum combustion air and exhaust pipe lengths will not be exceeded in
the planned installation. Also verify that the vent terminal can be located in accordance with Section VI.
4) Make sure that the boiler is correctly sized:
• For heating systems employing convection radiation (baseboard or radiators), use an industry accepted
sizing method such as the I=B=R Heat Loss Calculation Guide (Pub. #H21 or #H22) published by the
Hydronics Institute in Berkely Heights, NJ.
• For new radiant heating systems, refer to the radiant tubing manufacturer’s boiler sizing guidelines.
• For systems that incorporate other indirect water heaters, refer to the indirect water heater manufacturer’s
instructions for boiler output requirements.
• Long runs of venting may reduce the maximum input of the boiler by as much as 10% (See Section VI for
more information.
5) Make sure that the boiler received is congured for the correct gas (natural or LP).
6) Make sure that the boiler is congured for use at the altitude at which it is to be installed.
IV Locating the Boiler
1) Observe the minimum clearances shown in Figure 4.1. These clearances apply to both combustible and non-
combustible materials. Observe the minimum clearances to combustibles for vent pipe shown in Table 4.2.
2) Note the recommended service clearances in Figure 4.1. The recommended service clearances may be re-
duced to the minimum combustible clearances provided:
a. Access to the front of boiler is provided through a door.
b. Access is provided to the condensate trap and ttings/trim located on the back of the boiler.
3) Boiler may be installed on non-carpeted combustible surface.
4) The relief valve must be installed in the factory specied location.
5) The boiler should be located so as to minimize the length of the vent system.

V Air for Ventilation
Air for combustion must always be obtained directly from outdoors, however sufcient air for ventilation must
still be provided in the boiler room. Air for ventilation is required to keep various boiler components from over-
heating and is always obtained from indoors. To ensure an adequate ventilation air supply, perform the following
steps:
Step 1: Determine whether the boiler is to be installed in a conned space - A conned space is dened by the
National Fuel Gas Code as having a volume less than 50 cubic feet per 1000 BTU/hr input of all appliances
installed in that space. To determine whether the boiler room is a conned space:
1) Total the input of all appliances in the boiler room in thousands of BTU/hr. Round the result to the next
highest 1000 BTU/hr.
2) Find the volume of the room in cubic feet. The volume of the room in cubic feet is:
Length (ft) x width (ft) x ceiling height (ft)
In calculating the volume of the boiler room, consider the volume of adjoining spaces only if no doors are
installed between them. If doors are installed between the boiler room and an adjoining space, do not consider
the volume of the adjoining space, even if the door is normally left open.
3) Divide the volume of the boiler room by the input in thousands of BTU/hr. If the result is less than 50, the
boiler room is a conned space.
Example:
A T300 and a water heater are to be installed in a room measuring 10ft – 3 in x 10ft with an 8 ft ceiling. The
water heater has an input of 50,000 BTU/hr:
Total input in thousands of BTU/hr = (300,000 BTU/hr + 50,000 BTU/hr) / 1000 = 350 MBTU/hr
Volume of room = 10.25 ft x 10 ft x 8 ft = 820 ft3
820/350 = 2.34. Since 2.34 is less than 50, the boiler room is a conned space.
Step 2a: If the boiler is to be placed in a conned space, provide two openings into the boiler room, one near the
oor and one near the ceiling. The top edge of the upper opening must be within 12” of the ceiling and the bottom
edge of the lower opening must be within 12” of the oor (Fig 5.1). The minimum opening dimension is 3 inches.
• If the TRIUMPH boiler is the only gas-burning appliance in the boiler room, these openings must each
have a minimum free area of 100 square inches.
• If other gas-burning appliances are in the boiler room, size the openings in accordance with the appliance
manufacturer’s instructions or the National Fuel Gas Code. Minimum opening free area is 100 square
inches even if opening requirements for other appliances are less.

WARNING
OUTDOOR COMBUSTION AIR MUST BE PIPED TO THE AIR INTAKE. NEVER PIPE COMBUSTION
AIR FROM AREAS CONTAINING CONTAMINATES SUCH AS SWIMMING POOLS AND LAUNDRY
ROOM EXHAUST VENTS. CONTAMINATED COMBUSTION AIR WILL DAMAGE THE BOILER
AND MAY CAUSE PROPERTY DAMAGE, PERSONAL INJURY OR LOSS OF LIFE.
6) The combustion air piping must terminate where outdoor air is available for combustion and away from areas that
will contaminate combustion air. Avoid areas near chemical products containing chlorine, chloride based salts,
chloro/uorocarbons, paint removers, cleaning solvents and detergents.

Figure 5.1: Boiler Installed In A Conned Space, Ventilation Air From Inside
• If the total volume of both the boiler room and the room to which the openings connect is less than 50 cubic feet
per 1000 BTU/hr of total appliance input, install a pair of identical openings into a third room. Connect addi-
tional rooms with openings until the total volume of all rooms is at least 50 cubic feet per 1000 BTU/hr of input.
• The “free area” of an opening takes into account the blocking effect of mesh, grills, and louvers. Where screens
are used, they must be no ner than ¼” (4 x 4) mesh.
Step 2b: If the boiler is to be placed in an unconned space, the natural inltration into the boiler room will
provide adequate air for ventilation without additional openings into boiler room.

VI Venting
WARNING
Failure to vent this boiler in accordance with these instructions could result in unreliable boiler
operation, severe damage to the boiler or property, personal injury or death:
* Do not attempt to vent this boiler with galvanized, PVC, or any other vent system not listed in Table 4.
* Do not attempt to mix components from different approved vent systems.
* Do not obtain combustion air from within the building.
* Do not install a barometric damper or drafthood on this boiler.
* The vent system for this boiler must not be shared with any other appliance.
* Moisture and ice may form on the surfaces around the vent termination. To prevent deterioration,
surfaces should be in good repair (sealed, painted, etc.)
A. Vent System Design
There are four basic ways to vent this boiler:
• Horizontal (“Side Wall”) Twin Pipe Venting - Vent system exits the building through an outside wall.
Combustion air and ue gas are routed between the boiler and outdoors using separate pipes.
• Vertical Twin Pipe Venting - Vent system exits the building through a roof. Combustion air and ue gas are
routed between the boiler and outdoors using separate pipes.
• Horizontal (“Side Wall”) Concentric Venting - Vent system exits the building through an outside wall.
Concentric venting consists of a “pipe within a pipe”. Flue gas exits the building through the inner pipe and
combustion air is drawn into the boiler through the space between the inner and outer pipe.
• Vertical Concentric Venting - Vent system exits the building through the roof. Concentric venting consists of a
“pipe within a pipe”. Flue gas exits the building through the inner pipe and combustion air is drawn into the boiler
through the space between the inner and outer pipe.
All of these systems are considered “direct vent” because in all of them air for combustion is drawn directly from
the outdoors into the boiler. A description of each of these venting options is listed in Tables 6.1 and 6.5. For
clarity, these vent options are numbered from 1 to 10. One of the vent option columns in Table 6.1 or in Table
6.5 must match the planned vent and air intake system exactly. In addition, observe the following guidelines:
1) Approved vent systems - Use only one of the approved vent systems shown in Tables 6.1 or 6.5. These vent systems
fall into two basic categories:
• Twin Pipe Vent Systems - The standard approved vent systems are made of a special stainless steel alloy (AL29-
4C) for protection against corrosive ue gas condensate. They are designed to provide a gas tight seal at all
joints and seams so that ue gas does not enter the building. Each approved vent system has a unique method for
installation - do not attempt to mix components from different vent systems. A list of approved twin pipe vent
systems is shown in Table 6.4.
• Concentric Vent System - The concentric vent system may only be used on the T300. Each Triad concentric
vent component consists of an inner pipe of polypropylene and the outer pipe of steel. Integral gaskets on each
concentric tting provide a gas tight seal. In this manual, concentric pipe sizes are called out in terms of the inner
and outer pipe nominal diameters in millimeters. For example“100/150mm” pipe consists of a 100mm exhaust
pipe inside a 150mm diameter outer pipe. A list of all Triad concentric vent components is shown in Table 6.10.
The T399 and T425 are supplied with stainless steel vent collar and a separate air intake collar for twin
pipe venting. The T300 may be supplied with either a stainless steel vent adaptor kit (P/N 230557) for twin
pipe venting or a concentric vent adaptor kit (P/N 230556) for concentric venting.
2) Maximum Vent and Air Intake Lengths - The maximum length of the vent air intake piping depends upon the vent
option selected and the boiler size. See Tables 6.1 and 6.5 for the maximum vent lengths. All vent lengths shown in
Tables 6.1 and 6.5 are in addition to one 90° elbow and the termination tting.
3) Minimum Vent and Air Intake Lengths - Minimum vent length is 4ft. Minimum air inlet length is 2ft.
4) Permitted Terminals for Horizontal Venting (Vent Options 1,2&3)
• Vent Option 1, 2 & 3 - Exhaust terminal is either Triad PN 240513 (4” vent systems) or PN 240514 (5” vent
systems). The air intake terminal is a 90 degree elbow with a rodent screen supplied by the installer. This elbow is
made out of the same material as the rest of the air inlet system (either galvanized or PVC) and is installed as shown
in Figure 6.2.
• Vent Option 4 - Triad P/N 23569.
5) Horizontal Vent and Air Intake Terminal Location - Observe the following limitations on the vent terminal location
(also see Figure 6.7):
• Vent terminals must be at least 1 foot from any door, window, or gravity inlet into the building.
• Maintain the correct clearance and orientation between the vent and air intake terminals. The vent and air intake
terminals must be at the same height and their center lines must be between 12 and 36 inches apart. Both terminals
must be located on the same wall.
• The bottom of the vent and air intake terminals must be at least 12” above the normal snow line. In no case should
they be less than 12” above grade level.
• The bottom of the vent terminal must be at least 7 feet above a public walkway.
The Vent Option #1 column in Table 6.1 describes a horizontal direct vent system using 4” vent pipe. From this
column, we see that a T300 may have a vent length of up to 100ft. The rst 90 elbow and the termination tting are
not considered. From Table 6.6, the equivalent length of the 4” 45 elbow is 4.5ft and the equivalent length of the 4”
90 degree elbow is 8ft. The maximum allowable run of straight pipe on this system is therefore:
100ft – 4.5 ft – 8ft = 87.5ft
Since the planned installation has only 28 ft of straight pipe, the planned vent length is acceptable.
If additional elbows are desired, the maximum allowable vent length must be reduced by the amount shown in
Table 6.6 for each additional elbow used. Termination ttings are not counted when counting additional elbows.
Example:
A 4” twin pipe vent system is planned for a horizontally vented T300 which has the following components:
4 ft vertical pipe
1 90 elbow
10 ft horizontal pipe
1 90 elbow
6 ft horizontal pipe
1 45 elbow
8 ft horizontal pipe
1 termination tting

IMPORTANT
The length of the vent system has a minor impact on the maximum input of the boiler. The exact amount of this
de-rate is dependent upon a number of factors including the type of venting, number of joints in the vent system,
and the type of fuel. An estimate of the amount of de-rate that can be expected at the maximum vent length is as
follows:
T300: Less than 10%
T399, T425: Less than 2%
