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.

You must use the regulator supplied with heater even if pro-
pane tank has one.

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 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.
