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.

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. |
CAUTION: Use pipe joint sealant that is resistant to liquefied petroleum gases.
Install sediment trap in supply line as shown in Figure 6. Locate sediment trap where it is within reach for
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. |
