Code Approval

IMPORTANT:

PLEASE READ THE FOLLOWING

CAREFULLY

It is normal for fireplaces fabricated of steel to give off some expansion and/or contraction noises during the start up or cool down cycle.

Similar noises are found with your furnace heat exchanger or car engine.

IMPORTANT:

PLEASE READ THE FOLLOWING

CAREFULLY

It is not unusual for gas fireplace to give off some odor the first time it is burned. This is due to the manufacturing process.

Please ensure that your room is well ventilated during burn off — open all windows.

It is recommended that you burn your fireplace for at least ten (10) hours the first time you use it. Place the fan switch in the “OFF” position during this time.

 

WARNING

Never connect unit to private (non-utility)

 

 

 

 

gas wells. This gas is commonly known

 

 

as wellhead gas.

 

 

 

Direct Vent type appliances draw all combustion air from outside of the dwelling through the vent pipe.

These appliances have been tested by CSA and found to comply with the established standards for DIRECT VENT GAS FIREPLACE HEATERS in the USA and Canada as follows:

Vent installation

WDV Series Gas Fireplace

 

 

installation planning

There are two basic types of direct-vent installation:

Horizontal Termination

Vertical Termination

WARNING

Never run the vent pipe level or downward. This may cause excessive temperatures which could cause a fire.

It is important to select the proper length of vent pipe for

the type of termination you choose. It is also important to note the wall thickness. for horizontal termination

Select the amount of vertical rise desired.All horizontal run of venting must have 1/4" rise for every 12" of run towards the termination below 7Z\x feet of vertical rise. With 7Z\x feet or more vertical rise off top of fireplace, the horizontal run may run level. NEVER run vent piping down.

You may use up to three 90° elbows in this vent configuration. Refer to Vertical/Horizontal Termination Configurations on Page 14.

For vertical termination

Measure the distance from the fireplace floor to the ceiling.Add the ceiling thickness, the vertical rise in an attic or second story, and allow for sufficient vent height above the roof line.

NOTE: You may use two 45° elbows in place of a 90° elbow. You must follow rise to run ratios when using 45° elbows. The appliance is approved for use with three 90° elbows maximum or a combination of 90° and 45° elbows up to a maximum of 270°.

For two-story applications, firestops are required at each floor level. If an offset is needed in the attic, additional pipe and elbows will be required.

You may use a chase with a vent termination with exposed pipe on the exterior of the house.

Refer to Installing A Vent System in an Outside Chase below. If pipe is enclosed in chase, it is not exposed.

It is very important that the venting system maintain its balance between the combustion air intake and the flue gas exhaust. Certain limitations apply to vent configurations and must be strictly followed.

Installing a vent system in an outside chase

A chase is a vertical boxlike structure built to enclose venting that runs along the outside of a building. A chase is required for such venting.

NOTICE

When installing in a chase, you should insulate the chase as you would the outside walls of your home. This is especially important in cold climates. Insulation should be considered a combustible material. Maintain proper clearances to all combustible materials.

NOTICE

Treatment of firestops and construction of the chase may vary from building type to building type. These instructions are not substitutes for the requirements of local building codes. You must follow all local building codes.

WARNING

Always maintain minimum clearances around vent systems. The minimum clearances to combustibles for horizontal and vertical vent pipe are 1" at the top, sides and bottom of the vent system. Do not pack the open air spaces with insulation or other materials. This could cause high temperatures and may present a fire hazard.

VERTICAL/Horizontal termination configurations

Since it is very important that the venting system maintain its balance between the combustion air intake and the flue gas exhaust, certain limitations as to vent configurations apply and must be strictly adhered to.

The Vent Graph, showing the relationship between vertical and horizontal side wall venting, will help to determine the various dimensions allowable. Figure 10

NOTE: Horizontal and vertical sections of this vent system require a minimum of 1" clearance to combustibles at the top, sides and bottom.

When vent exits through foundations less than 20" below outcrop, the termination must be flush up with outcropped wall above.

It is best to locate the fireplace in such a way that minimizes the number of offsets and horizontal vent length.

The horizontal vent run refers to the total length of vent pipe from the flue collar of the fireplace (or the top of the Transition Elbow) to the face of the finished outside wall.

The maximum number of 90° elbows per side wall installation is three (3). Figure 11

Aminimum of 12" is required before a 90° elbow. If a 90° elbow is fitted directly after 12" vertical section mounted to the top of the fireplace, the maximum horizontal vent run before the termination or a vertical rise is 36” (914 mm). Figure 12

FP1176

Figure 11 -

Maximum Three (3) 90° Elbows Per Installation

If a 90° elbow is used in the horizontal vent run (level height maintained) the horizontal vent length is reduced by 36". Refer to Page 17, Figures 11 and 12. This does not apply if the 90° elbows are used to increase or redirect a vertical rise. Figure 14

Example:According to the vent graph (Page 13) the maximum horizontal vent length in a system with a 10' vertical rise is 17Z\x’ (5.3 m) and if a 90° elbow is required in the horizontal vent it must be reduced to 14Z\x' (4.4 m).

In Figures 13 and 14 dimension A plus B must not be greater than 17' (5.2 m).

The maximum number of 45° elbows permitted per side wall installation is two (2). These elbows can be installed in either the vertical or horizontal run.

For each 45° elbow installed in the horizontal run, the length of the horizontal run MUST be reduced by 18" (45 cm). This does not apply if the 45° elbows are installed on the vertical part of the vent system.

The maximum number of elbow degrees in a system is 270°. Figure 15

Below Grade Installations

When it is not possible to meet the required vent terminal clearances of 12" above grade level, a snorkel kit is recommended. It allows installation depth down to 7" (178 mm) below grade level. The 7" (178 mm) is measured from the center of the horizontal vent pipe as it penetrates through the wall.

Ensure that sidewall venting clearances are observed. If venting system is installed below ground, we recommendawindowwellwithadequateandproperdrainage to be installed around the termination area.

If installing a snorkel, a minimum 12" vertical rise is necessary. The maximum horizontal run with the 12” vertical pipe is 36". This measurement is taken from the collar of the fireplace (or transition elbow) to the face of the exterior wall. See the Sidewall Venting Graph for extended horizontal run if the vertical exceeds 12".

1.Establish vent hole through the wall.

2.Remove soil to a depth of approximately 16" below base of snorkel. Install drain pipe. Install window well (not supplied). Refill hole with 12" of coarse gravel leaving a clearance of approximately 4" below snorkel. Figure 16

3.Install vent system.

4.Ensure a watertight seal is made around the vent pipe coming through the wall.

5.Apply high temperature sealant caulking (supplied) around the 5" and 8" snorkel collars.

6.Slide the snorkel into the vent pipes and secure to the wall.

7.Level the soil so as to maintain a 4" clearance below snorkel. Figure 16

If the foundation is recessed, use recess brackets (not supplied) for securing lower portion of the snorkel. Fasten brackets to wall first, then secure to snorkel with self drilling #8 x 1/2" sheet metal screws. It will be necessary to extend vent pipes out as far as the protruding wall face.
