WARNING
!
!
Failure to install, operate or service this
appliance in the approved manner may
result in property damage, injury or death.
To connect the gas:
The gas supply to the infra-red heater must be
connected and tested in accordance with national, state,
provincial and local codes along with the guidelines in
the Dayton
®
High Intensity Heater 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 B149.2 Standard.
Important! Before connecting the gas supply to the
infra-red heater(s):
• Check that the gas piping and service has the
capacity to handle the load of all 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.
• Test and confirm that inlet pressures are correct.
Refer to the rating plate for required minimum and
maximum pressures (see Chart 2.3). The gas supply
pipe must be of sufficient size to provide the
required capacity and inlet pressure to the heater (if
necessary, consult the local gas company).
