VENTING INSTRUCTIONS
VENTING
The appliance will not function without being connected to a proper venting system.
This appliance may use 4” and 7” gas flex vents with NorthFire 3400 listed vent components, or Simpson
Duravent 4 x 6 5/8 direct vent systems with Simpson Dura vent Adaptor (999-DV-SDA). 7” dia. rigid vent
may directly replace 7” dia. flex vent in all applications.
For best venting performance using gas flex vent, here are some general venting rules that we
recommend:
1. Use only 4”and 7” diameter 2-ply certified gas flex vent in a co-axial configuration.
2. Maintain a minimum clearance of 1” to the sides and bottom and 2” to the top outside surface of the
vent pipe and combustible material.
3. Observe any local code restrictions, if any, regarding the installation of this type of gas appliance.
4. Observe the venting chart given in this manual.
5. Use a vent spacer between the inside and outside flex vents at 3 ft intervals.
6. Never slope horizontal running vents downwards.
7. Maintain at least an upward slope of 1” for every 1 ft of horizontal run on the rear vented models.
8. Terminate the vent with a vent termination supplied by Archgard Industries Ltd.
9. Support horizontal running vents every 3 ft to prevent it from sagging.
10.Wall terminal must be installed a minimum of 12” above grade measured from bottom of terminal.
Horizontal sections must be supported to prevent sagging. See vent manufacturer's installation manual
for more information - As a general guideline; a flex line should be supported every 2 - 3' (609.6 - 914.4
mm) and rigid pipe should be supported every 4 - 6' (1219.2 - 1828.8 mm)
This fireplace must be installed so as to prevent accumulation of condensate in the venting system.
VENT TERMINATION
1. See “ALLOWABLE TERMINATION LOCATIONS” diagram (page 15) to establish a suitable vent
termination location.
2. In heavy snowfall areas make sure vent termination is located where it can not be blocked by snow or
snow from snow removal equipment.
3. Locate vent termination away from plants, bushes or any other object on or near the vent termination
that will interfere or obstruct the air flow around it.
4. DO NOT recess vent termination into walls, sidings or planters.
5. Vent terminations located below 7ft from grade level or anywhere it can be a burn hazard to the public,
such as patios and balconies, must be protected with an Archgard-approved termination cage.
6. Always ensure bottom of Vent Terminal is a minimum of 12” above grade.
• Maximum horizontal vent length straight out the back or the unit is 3ft
• Maximum of one 45º elbow is allowed
• Maintain 1” vertical rise minimum per foot of horizontal length beyond 6”. ie: no vertical rise is required for
a 6” horizontal vent straight out the back of the fireplace
• For rear vent configurations other than above please refer to the vent charts on page 13 and vent restrictor
chart on page 14
VENTING FOR REAR VENTED APPLIANCES

3400-DVTR20N-3 13
VENTING INSTRUCTIONS
Maintain a minimum of 1” clearance to combus-
tibles on sides and bottom and 2” from top sur-
face of the vent. The gas fireplace is designed
and optimized for majority of the installations
with short vents. With taller vents, the efficien-
cy and flame characteristics will change. There-
fore, an exhaust restrictor plate is provided by
the manufacturer to preserve as much of the
original short vent performances as possible on
taller vent configurations.
Top/Rear Vent Units
Rear Vent Units
Maximum Horizontal run for Rear Vent is 36” from the back of the unit to termination or 16”
with a 45º elbow
Follow the venting instructions as strictly as possible to obtain the best
performance from the appliance.

VENTING INSTRUCTIONS Cont...
The rigid vent systems use twist lock connections. The adaptor attached to the unit connects to the approved
venting system. Assemble the vent system using the desired combination to sections and fittings required for
your particular installation. While you are assembling the pipe bear in mind the best visual appearance. Seams
should be aligned and hidden as much as possible. Make sure you twist the mating section all the way to make a
solid connection.
Note: As this system is a sealed system, a high temperature sealing compound must be used to seal the
metal to metal joint.
Vent Pipe Assembly Procedure
The female section of the pipe/fitting has four indenta-
tions evenly spaced around the pipe. These indentations
are designed to slide over the male section of the pipe and
locate into the four entry slots of the male section of pipe.
Twist the female section clockwise a quarter turn to fully
lock the sections together.

3400-DVTR20N-3 18
GAS CONNECTIONS
Before connecting the appliance to the gas supply line, double check that the appliance
you have purchased is designed for the gas type you are using. The gas type markings
are located on the certification label and also on the appliance’s gas valve.
Provide adequate clearance for proper installation and checking of the gas connections.
Have your gas supplier or a qualified gas fitter run a gas supply line into the gas
fireplace. The line must be properly sized and fitted according to the installation codes.
Upstream of the appliance supply connection, the fitter shall provide an easily
accessible manual shut-off valve.
CAUTION: The appliance and its individual shutoff valve must be disconnected
from the gas supply piping system during any pressure testing of that
system at test pressures in excess of 1/2 psig (3.5 kPa). The appliance
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 (3.5
kPa). Failure to do so will damage the appliance’s gas valve. Such
damage is not covered by the manufacturer’s warranty.
Check for proper gas supply pressure by loosening the set screw on the supply pressure
tap (marked IN) on the gas valve with a small flat tip screw driver and placing a test
gauge on the tap.
The minimum permissible gas supply pressure is 4.5 in. w.c. (1.12 kPa) for natural gas
and 11.0 in. w.c. (2.74 kPa) for propane. Maximum gas supply pressure should never
exceed 7 in. w.c. (1.74 kPa) or 1/2 psi. for natural gas and 13 in. w.c propane.
BE SURE TO TIGHTEN THE PRESSURE TAP SET SCREW AFTER
CHECKING THE PRESSURE. CHECK ALL GAS CONNECTIONS FOR GAS
LEAKS.
