General Information
The Dutchwest Direct Vent/Natural Vent Room Heater,
Model Nos. 3070, 3071, 3072 and 3073, is a vented gas
appliance listed to the ANSI standard Z21.88b-2001 and
CSA-2.33b-2001 for Vented Room Heaters, and CSA 2.17M91, Gas-Fired Appliances For Use at High Altitudes.
The installation of the Dutchwest Direct Vent/Natural
Vent Room Heater must conform with local codes, or in the
absence of local codes, with National Fuel Gas Code, ANSI
Z223.1/NFPA 54 — latest edition and CSA B-149.1 Instal
lation Code. (EXCEPTION: Do not derate this appliance
for altitude. Maintain the manifold pressure at 3.5” w.c. for
Natural Gas and 10.0” w.c. for LP gas at maximum input.)
This appliance is only for use with the type of gas indicated on the rating plate. This appliance is not convertible for
use with other gases unless a certified kit is used.
Installation and replacement of gas piping, gas utilization equipment or accessories, and repair and servicing
of equipment shall be performed only by a qualified
agency. The term “qualified agency” means any individ
ual, firm, corporation, or company that either in person
or through a representative is engaged in and is responsible for (a) installation or replacement of gas piping,
or (b), the connection, installation, repair, or servicing
of equipment, who is experienced in such work, familiar
with all precautions required, and has complied with all
the requirements of the authority having jurisdiction.
The Dutchwest Direct Vent/Natural Vent Room Heater
should be inspected before use and at least annually by
a qualified service agency. It is imperative that control
compartments, burners, and circulating air passageways of the appliance be kept clean.
The Dutchwest Direct Vent/Natural Vent Room Heater and
its individual shut-off 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 Direct Vent/Natural Vent Room Heater
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 less than 1/2 psig.
‘Direct Vent’ describes a sealed combustion system in
which incoming outside air for combustion and outgoing
exhaust enter and exit through two separate concentric
passages within the same sealed vent system. The system
does not use room air to support combustion. The Direct
Vent system permits the gas appliance to be vented directly
to the outside atmosphere through the side of the house or
vertically through the roof. Conventional venting systems
(Natural Vent) take air from the room for combustion and
vent the exhaust vertically through the roof to the atmosphere.
This appliance is approved for bedroom installations in the
U.S. and Canada.
This appliance may be installed in an aftermarket* manufactured (mobile) home, where not prohibited by state or
local codes.

Vent Termination Clearances
When planning the installation, consider the location
of the vent terminal and clearances. Some of the most
common clearances to keep in mind are shown in Figure 10.
Important: All vent clearances must be maintained.
Check your vent termination clearances against
Figures 9 through 11.
The vent should be placed so that people cannot be
burned by accidentally touching the vent surfaces when
the stove is operating.
The vent termination should be located where it cannot
be damaged by such things as automobile doors, lawn
mowers or snowblowers and it should be located away
from areas where it could become blocked by snow,
etc.
Some considerations are:
• Obstructions or impediments to venting.
• Nearby combustible materials that could come into
contact with combustion exhaust gases.
• Other nearby openings {within 12” (305mm)} through
which exhaust gas could reenter the building.
• All vegetation within 3’ ((76mm) that may interfere
with the draft.
Other factors that influence where the installation will
be sited include the location of outside walls, where
additional heat may be desired in the home, where the
family members gather most regularly, and perhaps
most importantly, the distance limitations of the venting
system.
IMPORTANT
Direct Vent Only
• The horizontal termination must not be recessed
into the exterior wall or siding.
• Horizontal vent runs must be level toward the vent
termination.
• Clearances around the vent termination must be
maintained.
• For installations using Simpson DuraVent pipe,
parallel installations with minimum wall clearance
have restricted access for connecting the Horizontal Vent Cap straps to the vent pipe. See the
maker’s instructions for recommended installation
procedures.
ST132a
30001935
Dutchwest Direct Vent / Natural Vent Gas Heater
Venting Termination Clearances
Your stove is approved to be vented either through the
side wall, or vertical through the roof.
• This unit does not require any opening for in-
spection of vent pipe.
• Only CFM Corporation and Simpson DuraVent
venting components specifically approved and
labelled for this stove may be used.
• Minimum clearances between vent pipes and
combustible materials is one (1”) inch (25 mm),
except where stated otherwise.
• Venting terminals shall not be recessed into a wall or
siding.
• Horizontal venting must be installed on a level plane
without an inclining or declining slope.
There must not be any obstruction such as bushes,
garden sheds, fences, decks or utility buildings within
24” from the front of the termination hood.
Do not locate termination hood where excessive snow
or ice build up may occur. Be sure to check vent termination area after snow falls, and clear to prevent accidental blockage of venting system. When using snow
blowers, make sure snow is not directed towards vent
termination area.
Location of Vent Termination
It is imperative the vent termination be located observing the minimum clearances as shown on this page.
