Connect to Gas Supply
Before connecting the appliance, turn off all gas appli-
ances. Close the main gas valve at the gas meter or Lp
tank. Make certain there is good ventilation where the
installation will be made. Installation should comply with
all applicable building codes and ANSI Z223.1, latest
edition. Use LP gas resistant pipe compound to seal
threaded joints.
An installer supplied, design certified gas pressure
regulator must be installed to bring the gas supply
pressure down to 14” w.c.
WARNING: Never connect an unregulated gas line
to the heater.
IMPORTANT: Check gas line pressure before connect-
ing heater to gas line. Gas line pressure must not be
higher than 14” w.c. If gas line pressure is higher,
heater gas pressure regulator damage could occur.
NOTE: The gas line connection can be made with 3/8”
black or steel pipe. Internally tinned copper tubing may
be used in certain areas. Check your local codes. Use
pipe of large enough diameter to allow proper gas
volume to heater. If pipe is too small, undue pressure
loss will occur.
CAUTION: Use pipe joint sealant that is resistant to
liquefied petroleum gases.

Floor Installation
1. Heater may only be installed on a noncombustible
flat surface. Wall mounting screws may be used to
keep heater from side movements.
2. Measure heater mounting screw location “X” as
desired above floor. (Fig. 5)
3. Use enclosed “paper template” for proper distance
between holes. Be sure template is level. It may be
necessary to use plastic or lead anchors for plaster
wall.
4. Drill holes at marked locations using 9/64” drill bit.
5. Leave screw head out from wall far enough to attach
heater.
