OPERATION
Use only a 20 lb. propane/LP cylinder (not
included). See safety information for proper
cylinder selection. Connect hose/regulator
assembly to propane cylinder (see Figure
12). Hose should already be connected to
heater. When connecting regulator assembly
to cylinder valve, hand tighten nut clockwise
to a positive stop. DO NOT use a wrench to
tighten. Use of a wrench may damage quick
closing coupling nuts and result in a hazard
-
ous condition.
Route retention chain through at least one
handle of propane/LP tank (see Figure 12).
Make sure to route chain through handle on
tank and NOT around tank valve. Chain must
not interfere with valve. Attach hooks on both
ends of chains to ring retainers installed on
burner support plate. See Figure 7, page 6.

3. Use a noncorrosive leak detection solution
to check the connection. For leaks before
attempting to light heater. If leak is found,
turn cylinder valve to CLOSE and do not
use until all leaks are corrected.
