WARNING: Review and understand the warnings
in the Safety Information section, pages 2 and 3. They
are needed to safely operate this heater. Follow all
local codes when using this heater.
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.

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: Posi-
