The size of the gas supply lines must comply with local codes and recommendations of the local gas company. United States: Refer to National Fuel Gas Code, ANSI

Z223.1 - latest revision (same as NFPA 54). Canada: Refer to CSA B149.1 Natural Gas ans Propane Installa- tion Code.

A 1/8" NPT plugged tap must be installed in the gas line connection immediately upstream of the burner that is farthest from the gas supply meter. The tap is required

for checking system gas pressure.

4.2.3 Meter and Service

Meter and service must be large enough to handle all the heaters being installed plus any other connected load. The gas line which feeds the system must be large enough to supply the required gas with a maximum pressure drop of 1/2" wc When gas piping is not included in the layout drawing, the local gas supplier will usually help in planning the gas piping.

4.3 Electrical Service Requirements

WARNING

Electrical Shock Hazard

Plug heater into grounded three- prong ceiling receptacle.

Do not cut or remove the grounding prong from this plug.

Do not use with an extension cord.

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

The CGTH-Series heater requires a grounded three- prong electrical outlet to be installed within 18" of the rear surface of the heater’s burner box. It is recom- mended that the outlet for the heater be ceiling- mounted and should be on a dedicated circuit. DO NOT use an electrical extension cord to operate the heater.

Heater Rating: 120 VAC, 60 Hz, 1 Ø, 1 A

4.3.1 Grounding

The heater must be electrically grounded in accordance with the following codes: United States: Refer to National Electrical Code, ANSI/NFPA-70 - latest revision. Wiring must conform to the most current National Electrical Code and local ordinances. Canada: Refer to Canadian Electrical Code, CSA C22.1 Part 1 - latest revision.

4.3.2 Thermostat

It is important to note that the CGTH-Series heater is controlled by a low voltage (24V AC) thermostat sup- plied with the heater. The control transformer located inside the burner supplies the necessary electrical power to operate the thermostat. No other electrical power to the thermostat is required.
