8. During any pressure testing of the system at pressures
in excess of 1/2 psig (14 inch W.C.)., disconnect the
heater at the heater manual shutoff valve (located at
the end of the supplied gas train) from the gas supply
piping system.
9. Ensure the supply pressure is regulated by a non-
stacking, tight, shut-off regulator.
10. Arrange gas piping so that it does not interfere with
any cover or burner, inhibit service or maintenance,
or prevent access between unit and walls or another
unit.The burner assembly and gas controls terminate
at a manual stop valve to which the gas supply should
be connected. Piping must be sized for a gas fl ow
consistent with the required BTU/Hr input. Large
pressure drops must be avoided. Fulton recommends
that the supply piping between the pressure regulator
and the inlet to the heater be kept to a minimum. The
minimum required gas pressure at the stop valve varies
0-400 PSIG

with the model of heater. The requirements for natural
gas-fi red coil design models are as follows:
 Models FT-0080-C to FT-0400-C 14”w.c.
 Models FT-0600-C to FT-0800-C 60”w.c.
 Models FT-1000-C to FT-1400-C 120”w.c.
NOTE:

Note: Low emissions burners for all models
require 5 psi.
NOTE:  Even when the unit is shut down, the gas supply
pressure must never exceed these values.
NOTE:

When operating, the supply pressure must not drop
below these limits: Not less than 11 “ w.c. where 14” w.c is
required. Not less than 50” w.c. where 60” w.c. is required.
Not less than 100” w.c. where 120” w.c. is required.
