Gas Supply
The gas supply to the infrared patio heater must be connected and tested in accordance with national,
state, provincial, and local codes along with the guidelines in the manual. In the United States refer to the
latest edition of the ANSI Z223.1 (NFPA 54) standard; and in Canada, refer to the latest edition of the
CAN/ CGA B149.1 Standard.
Supply gas piping to the unit should conform to the local and national requirements for type and volume of
gas handled, and pressure drop allowed in the line. Avoid pipe sizes smaller than 1/2”.
IMPORTANT! Before connecting the gas supply to the heater:
• Verify that the heaters’ gas type (as listed on the rating plate) matches that of your application and the
installation complies with national and local codes and requirements of the local gas company.
• Unless otherwise noted on the rating plate, the infrared heater is designed and orificed to operate on
standard BTU gas. Contact the factory if utilizing non-standard BTU gas.
• Check that the gas piping and service has the capacity to handle the total gas consumption of all the
heaters being installed, as well as any other gas appliances being connected to the supply line.
• Check that the main gas supply line is of proper diameter to supply the required fuel pressures.
• If utilizing used pipe, verify that its condition is clean and comparable to a new pipe. Test all gas
supply lines in accordance with local codes.
The gas outlet must be in the same space as the appliance installation, and must be accessible. It may
not be concealed within or run through any wall, floor or partition. When installing the heater in a corrosive
environment (or near corrosive substances), use a gas connector suitable for the environment. Do not
use the gas piping to electrically ground the heater.
This heater is equipped to connect to ½” NPT gas pipe. All piping must be installed in accordance with the
requirements outlined in the National Fuel Gas Code ANSI/Z223.1 (latest edition) or CSA B149.1 and
B149.2. Support all gas piping with pipe hangers, metal strapping, or other suitable material. Do not rely
on the heater to support the gas pipe.
WARNING
!
Improperly connected gas lines may result in fire, explosion,
poisonous fumes, toxic gases, asphyxiation and death.
Connect gas lines in accordance to national, state, provincial
and local codes.
NOTICE
The total input to the appliance must fall within +/- 5% of the rated input as indicated on the rating plate.
Otherwise the burner may prematurely fail.
