SECTION 6 - GAS PIPING
Read applicable warnings on page 1 & 2 before proceeding with Gas Pipe installation. Improper installation may result in property damage,
severe injury, or death.
Meter and service must be large enough to handle all the burners 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" water column. Local gas supplier will usually
help in planning the correct gas piping size.
A 1/2" pipe at each burner location must be located and oriented as shown in (Figure 14) . To check system pressure, put a plugged 1/8" NPT tap in the
gas line at the connection to the burner farthest from the supply. Before connecting the burners to the supply system, verify that all high pressure testing
of the gas piping has been completed. Do not high pressure test the gas piping with the burners connected.
Follow these instructions to ensure a professional gas supply installation:
• Support all gas piping with suitable pipe hanging materials.
• Use wrought iron or wrought steel pipe and malleable iron fitting. All pipe fittings should be new and free from defects.
• Use L.P. gas-resistant joint compound on all pipe threads.
• Check the pipe and tubing ends for leaks before placing heating equipment into service. When checking for gas leaks, use soap
and water solution: NEVER USE AN OPEN FLAME.
Install the flex gas connector as shown. The flex gas connector accommodates expansion of the heating system and allows for easy installation
and service of the burner. The shut-off valve must be parallel to burner gas inlet. The 2" displacement shown is for the cold condition. This
displacement may reduce when the system is fired.

SECTION 7 - WIRING
Heaters are normally controlled by thermostats. Line voltage thermostats are wired directly (see Figure 16), 24V thermostats are wired directly using
the terminals on burner box(see Figure 18). Heaters must be grounded in accordance with the National Electric Code ANSI/NFPA-70 or current
Canadian Electrical Code, CSA C22.1. Heaters may also be controlled with a manual line voltage switch or timer switch in place of the thermostat.
• NOTE: Jet heaters come with the thermostat connection jumped out with a piggyback connector inside the burner box to pro-
vide a constant call for heat. If the themostat junction needs utilized, you will need to open up the box and attach these wires
to the bushing on the back of the burner box.
