Equipment shall be installed in a location in which the facilities
7.
for ventilation permit satisfactory combustion of gas, proper
venting, and maintenance of ambient temperature at safe limits
under normal conditions of use. Equipment shall be located so
as not to interfere with proper circulation of air. When normal
inltration does not provide the necessary air, outside air shall
be introduced.
(See “Combustion and Ventilation Air”)
Advise owner to keep air passages free of obstructions. Ven-
8.
tilating and combustion air must enter boiler room without
restrictions.
e boiler shall be installed such that the automatic gas ignition
9.
system components are protected from water (dripping, spray-
ing, rain, etc.) during appliance operation and service (conden-
sate trap, control replacement, etc.).
Select level location as centralized with piping system, and as
1.
near chimney as possible.
Place crated boiler at selected location, remove crate by pulling
2.
crate sides from top and bottom boards.
is boiler must be set on non-combustible oor or optional
3.
non-combustible Base Plate placed over the top of a combusti-
ble oor. Refer to Repair Parts and Optional Kits for additional
detals (3-6 section Boiler Base Plate Part #14614031; or 7-9
Section Boiler base Plate Part #14614032). A combustible oor
is dened as materials made of or surfaced with wood, com-
pressed paper, plant bers, or other materials that are capable
of being ignited and burned. Such material shall be considered
combustible even thought ame-proofed, re-retardant treated,
or plastered. is boiler must not be installed on carpeting.
Boiler is to be level. Metal shims may be used under base legs
4.
for nal leveling.
Additional clearance for service may exceed clearance for re
5.
protection. Always comply with the minimum re protection
clearance shown on the boiler. An 18 inch clearance should
be maintained on any side where passage is required to access
another side for cleaning, servicing, inspection or replacement
of any part that may need attention.
To determine minimum clearances to combustibles refer to Ta-
6.
ble 2b, for rooms with a single boiler only. Rooms that are large
in comparison with the size of the boiler are dened as rooms
having a volume equal to or greater than 16 times the volume of
the boiler. Where the actual ceiling height of a room is greater
that 8’ the volume of a room shall be gured on the basis of a
ceiling height of 8’. Determination of room size should be based
on the total volume of all gas red equipment install in the
room. Consult the latest revision of the National Fuel Gas Code
for further information.
