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 Duravent 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.
VENT TERMINATION
1. See “ALLOWABLE TERMINATION LOCATIONS” diagram (page 13) 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.
VENTING FOR REAR VENTED APPLIANCES
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 11 and vent
restrictor chart on page 12..
Northfire 3400 11
Follow the venting instructions as strictly as possible to obtain the best
performance from the appliance.
**Top/Rear Conversion Instructions Pg. 30**
VENTING INSTRUCTIONS
Top/Rear Vent Units
Maintain a minimum of 1” clearance to combustibles 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 efficiency and flame characteristics will change.
Therefore, 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.
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
