Dutchwest Natural Vent Gas Heater
30002008
Connect the Gas Supply Line
Check the Rating Plate attached by a steel cable to the
firebox, to confirm that you have the appropriate firebox
for the type of fuel to be used. The Dutchwest may be
converted from one gas to another using the appropri-
ate Fuel Conversion Kit listed on Page 23.
This appliance should only be
connected by a qualified gas techni-
cian. Test to confirm manifold
pressures as specified below.
The Dutchwest Heater and its individual shutoff
valve must be disconnected from the gas supply
piping during any pressure testing of that system
at test pressures in excess of 1/2 psig (3.5 kPa).
The Dutchwest Heater must be isolated from the
gas supply piping system by closing its indi-
vidual manual shutoff valve during any pressure
testing of the gas supply piping system at test
pressure equal to or less than 1/2 psig.
There must be a gas shutoff between the stove
and the supply.
In order to connect Natural Gas, use a fitting with
3/8” NPT nipple on the valve side and 1/2” natural
gas supply line with an input of 28,000 BTUs at a
manifold pressure of 3.5” and a minimum inlet
supply pressure of 5.5” w.c.
In order to connect Propane, use a fitting with
3/8” NPT nipple on the valve side and 1/2” pro-
pane gas supply line with an input of 26,000
BTUs at a manifold pressure of 10.0” and a
minimum inlet supply pressure of 11.0” w.c.
In the U.S.; Gas connection should be made in accor-
dance with current National Fuel Gas Code, ANSI
Z223.1/NFPA 54. Since some municipalities have
additional local codes, be sure to consult you local
authority.
In Canada; consult the local authority and CSA-B149.1
installation code.
Connect the gas supply and test for leaks. Use a 50/50
solution of liquid soap and water to test for leaks at gas
fittings and joints. Apply water/soap solution with brush
only -
do not over apply. NEVER test with an open
flame. Light the pilot according to the directions on
Page 14, before going to the next step.

Fig. 18 Install decorative pipe over the B-vent pipe.
Attach the first section of venting to the B-vent adapter.
Depending on the length of the individual venting
sections and the lengths of the decorative pipe, you
may need to slip the decorative pipe over the venting
sections before attaching upper sections to lower ones.
The sections of decorative pipe should be oriented with
their seams (if any) toward the wall; sections usually
do not need to be fastened at each joint, other than slip
sections. The decorative pipe need not be fastened to
the locating bracket on the stove. If the layout includes
a slip section, this should be the last section of pipe
visible in the room at the ceiling. Refer to Page 7,
Figure 6 for details on joining the decorative pipe at the
ceiling.
