FRESH OUTSIDE AIR OPENING REQUIREMENTS
HEATER SIZE SQ. FT. OPENING
200,000 Btu/Hr 6.0
WARNING: Provide at least a 6 square foot open-
ing of fresh, outside air while running heater. If proper
fresh, outside air ventilation is not provided, carbon
monoxide poisoning can occur. Provide proper fresh,
outside air ventilation before running heater.
INSTALLATION
1. Provide propane supply system (see Propane Supply, page 3).
2. Connect fuel gas fitting on hose/regulator assembly to pro-
pane tank(s). Turn fuel gas fitting counterclockwise into threads
on tank. Tighten firmly using a wrench.
IMPORTANT:
Tighten
regulator with vent pointing down. Pointing vent down pro-
tects regulator from weather damage.
3. Connect hose to the valve inlet. Tighten firmly using a wrench.
You must use the regulator supplied with heater even if pro-
pane tank has one.
4. Open propane supply valve on propane tank(s) slowly.
Note:
If not opened slowly, excess-flow check valve on propane tank
may stop gas flow. If this happens, you may hear a click inside
the regulator assembly, this is the check valve closing. To re-
set the excess-flow check valve, close propane supply valve
and open it again slowly.
5. Check all connections for leaks. Apply mixture of liquid soap
and water to gas joints. Bubbles forming show a leak that must
be corrected.
6. Close propane supply valve.
WARNING: Test all gas piping and connections
for leaks after installation or servicing. Never use an
open flame to check for a leak. Apply a mixture of
liquid soap and water to all joints. Bubbles forming
show a leak. Correct all leaks at once.
