SECTION 3: CRITICAL CONSIDERATIONS

3.7 Gas Supply

WARNING

Fire Hazard

Connect gas supply according to Figure 15.

Do not use gas supply pipe and electrical connections to support heater’s weight.

Gas can leak if not installed properly.

Failure to follow these instructions can result in death, injury or property damage.

It is important that the gas supply pipe is sized correctly to provide the inlet pressure as stated on the heater data plate. The gas supply pipe and electrical connections must not support any of the heater's weight. See Page 22, Section 8

3.8 Electrical Supply

WARNING

Electrical Shock Hazard

Disconnect electrical and gas supply before servicing.

This appliance must be connected to a properly grounded electrical source.

Failure to follow these instructions can result in death or electrical shock.

A permanent 120 V / 1 Ø / 60 Hz electrical supply is required for the main electrical power. The heater also requires suitable controls in accordance with See Page 23, Section 9.

3.9 Vent

Choose heater orientation to allow for the proper location of the vent. Each heater must be fitted with a correctly sized sealed vent system.

If vented horizontally, no other appliance may be connected to the vent. See Page 14, Section 6.

Figure 4: Installation Clearances and Clearances to Combustibles

*Recommended mounting height varies with heater input. Heaters may be mounted at a higher level if destratification fans are installed.

Clearance to Vent: 2" (5 cm)

**18" (45.7 cm) minimum is necessary for servicing.

The heater must always be installed at least 6' (2 m) above the floor. The vent pipe must have clearance from combustibles by 2" (5 cm).

If installed at low levels where individuals can come in contact with hot heat exchanger components, adequate guarding must be provided.
