SL11B & S1500 Manual 934-6644 - Page 7
INSTALLATION
The Sure Flame Models SL11B & S1500 are direct fired gas heaters
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 ventila-
tion be 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 feet from any LP-
gas container, and allow the following clearance from any combusti-
ble materials:
Front Outlet: 20 feet (6 M) Sides: 2 feet (0.6 M
Intake: 2 feet (0.6 M) Top: 4 feet (1.2 M)
Front Outlet must not be directed at any LP-gas container within 20
feet (6M).
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.
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 as specified
on the rating plate. For protection against shock hazard the supply cord
must be plugged directly into a properly grounded three-prong recep-
tacle.
6 In all applications install the heater in such manner that it is not
directly exposed to water spray, rain and/or dripping water.
