CAUTION: Do not stand in
front of heater while lighting.
Stand at the side when lighting
the heater.
Use only a 20 lb. propane/LP cylinder (not
included). See safety information for proper
cylinder selection. Connect the hose/regula-
tor assembly to the cylinder (see Figure 3).
The hose should already be connected to the
heater. Connect hose to the valve inlet (see
Figure 3). Tighten firmly using a wrench.
Route retention chain through at least one
of the handles of the propane/LP tank (see
Figure 3). 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 chain retain-
ers installed on cabinet base.
