The gas supply line connection is made to the
Champlain’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
(see figure 14)
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 15.

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).
