Installation
The Sure Flame Model S1505B is a direct fired gas heater intended to be
used primarily for the temporary heating of buildings under construction,
alteration, or repair. Since all the products of combustion are released into
the area being heated, it is imperative that adequate ventilation is provided.
The flow of supply air and combustion gases must not be obstructed in any
way. Do not use the heater with ductwork as this will restrict the flow of supply
air.
1 Install the heater in a horizontal position at least 6 ft. (1.83 m) from any
LP-gas container, and allow the following clearances from any combus-
tible materials:
Front Outlet: 20 feet Sides: 2 feet
Intake: 2 feet Top: 4 feet
Front Outlet must not be directed at any LP-gas container within 20 feet.
Also make sure that no flammable vapours are present in the space
where the heater is being used.
2 When connecting the heater to a natural gas or propane supply line
ensure that the pressure at the heater inlet is within the specified range.
Please refer to Propane and Natural Gas Installation sections in this
manual. Excessive pressure (over 1/2 psig) will damage the controls
and void the warranty.
3 Visually inspect the hose assembly and ensure that it is protected from
traffic, building materials, and contact with hot surfaces. If it is evident
that there is excessive abrasion or wear, or the hose is cut, it must be
replaced.
4 After installation, check the hose assembly for gas leaks by applying a
water and soap solution to each connection.
5 Connect the heater to an adequate 115 volt electrical supply and in
compliance with the National Electrical Code, ANSI/NFPA 70. For
protection against shock hazard the supply cord should be plugged
directly into a properly grounded three-prong receptacle.
6 In all applications install the heater in such a manner that it is not directly
exposed to water, spray, rain and/or dripping water.
