ONNECTIONS
The gas supply line connection is made to the
Santa Fe’s gas control valve located under the
unit on the left side using a 3/8" NPT fitting.
The pipe must be sized to provide sufficient gas
supply to meet the maximum demand of the
unit. The supply line must include a manual
shut-off valve and union so that the unit can be
disconnected for servicing.
Use of a dedicated sediment trap is required by
code, and by Hearthstone. Damage to
components caused by the lack of a sediment
trap is not covered by warranty.
Once connected to the gas supply, the gas inlet
pressure, and manifold gas pressure, must be
tested. The gas control valve has built in
pressure taps for test gauge connections. The
supply line pressure must be tested to ensure it
meets the minimum pressure for the type of fuel
in use (NG or LP).
Pressure Measurements:
To measure the gas
pressures, connect a manometer to the gas inlet
tap (6) and manifold pressure tap (7)
in Figure
11.

DJUSTMENT
A qualified technician must connect the heater to
the gas supply, and leak test the unit before it is
approved for use. Consult all applicable codes.
The appliance, and its main gas valve, must be
isolated from the gas supply piping system by
closing its individual manual shutoff valve
during any pressure testing of the gas supply
piping system at test pressures equal to or
greater than ½ psig (3.5kPa).
