3.Installation and repair should be done by a qualified service person. The room heater should be inspected before use and at least annually by a professional service person. More frequent cleaning may be required due to excessive lint from carpeting and other materials. It is imperative that the control compartments, burners and circulating air passageways of the heater be kept clean.

CONNECTING TO GAS SUPPLY :

WARNING : Never connect an unregulated gas line to the heater.

An installer supplied, design certified gas pressure regulator must be installed to bring the gas supply pressure down to 14 inches of water column.

IMPORTANT : Check gas line pressure before connecting heater to gas line.

Gas line pressure must not be higher than 14 inches of water. If gas line pressure is higher, heater gas pressure regulator damage could occur.

CAUTION : Use only new, black iron or steel pipe and 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.

Typical Gas Supply Pipe Diameters

30,000 BTU/HR Model 3/8" or greater

CAUTION:

Use pipe joint sealant that is resistant to liquefied petroleum gases.

Install sediment trap in supply line as shown in Figure 8 Gas Connection. Locate sediment trap where it is within reach for cleaning. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed wrong, heater may not run properly.
