PRE-INSTALLATION PREPARATION

Location and Space Requirements

These are a few facts that can help you understand and enjoy your vented decorative ﬁ replace:

• The (V)CB36(N,P)(E) series of vented decorative ﬁ replaces may be recessed into an exterior chase, an interior ﬂ ush wall enclosure or a framed-in corner

installation.

• Models (V)CB36(N,P) are equipped with a millivolt gas control system that does not require electricity to operate. A piezo ignitor is provided to light the pilot without using matches or lighters.

• Models (V)CB36(NE/PE) are equipped with an electronic ignition system that requires 120VAC to operate. An electrode ignitor automatically lights the pilot ﬂ ame when the ﬁ replace is turned on.

• These ﬁ replaces can accept any approved 4” B-Type venting system and must be terminated vertically through the roof

using a listed type vent cap only. See venting instructions on

pages # and # for proper venting requirements.

• These vented ﬁ replaces require indoor air for combustion and must be installed in a room of sufﬁ cient size to provide adequate fresh air for safe and proper operation. The room intended for installation must be of sufﬁ cient size to meet the requirements for an unconﬁ ned space as deﬁ ned in the

Section 5.3, Air for Combustion and Ventilaton.

National Fuel Gas Code, ANSI Z223.1/NFPA 54,

If sufﬁ cient air for

combustion is not available a make-up air kit model AK4 may be

required to provide outside air to this appliance. Check your local codes as to speciﬁ c requirements for make-up air.

• This ﬁ replace may be installed in any room of the house provided all local codes and these installation instructions are followed.

• Do not install aftermarket vent dampers. Manual or Auto matic vent dampers are not approved for use with this appliance.

• Your ﬁ replace is designed to be used in zero clearance installa tions. Wall or framing material can be placed directly against any exterior surface on the back, sides, or top of your ﬁ replace, except when clearances are required from ﬂ ue vent pipe. See

Clearances

on page 5.

• If recessed into a wall, you can avoid extra framing by position ing your ﬁ replace against an already existing framing member.

• A hearth extension is not required with this appliance. If one is installed, it is for austhetic purposes only and does not have to meet standard requirements for hearth extensions.

• If you plan on installing a television or entertainment center re cessed above your ﬁ replace, it is recommended that you main tain a minimum 18” above the top of louver opening.

• When locating the termination cap, it is important to observe the minimum vent height and clearances required under code, see

Venting Installation Instructions

, page 7.

• Do not recess termination cap into a wall or siding.

• You may paint the termination cap with 450°F (232°C) heat resistant paint to coordinate with the exterior ﬁ nish.

PRE-INSTALLATION PREPARATION

LOCATION AND SPACE REQUIREMENTS

VENTING INSTALLATION

A 4" B-type venting system must be connected to the appliance for venting to the outside of the building.

The following section is provided as a guide to install a standad B-type vent installation.

Standing codes requirements concerning B-type vent installations may vary within your state, province or local codes juristdition. Therefore, it is recommended that you check with your local building code authority for speciﬁ c requirements or in absence of local codes, follow Section 7.0 of the current

Code NFPA No. 54/ANSI Z223.1

or in Canada with

B149 for Category I systems using double wall B-1 vent pipe.

This gas appliance must be vented to the outdoors only and may not be terminated into an attic space or into a chimney ﬂ ue servicing a solid-fuel burning appliance.

This appliance may be vented through a manufactured chimney liner system if all are listed, inspected and approved by local codes and/or building authorities.

CHECKING FOR PROPER VENTING

VENTING INSTALLATION

Example 1:

Shows the minimum allowable system height and

Continued

lateral offset for a 60° degrees or greater inclination. Code speciﬁ es that offsets at 60° degrees or greater are considered horizontal and must follow the 75% percent rule for lateral to total certical system height. Codes also allows only one offset in the total system when at 60° degrees or greater. The total vertical height in this example represents the minimum height of 8 feet and therefore the allowable lateral is 6 feet when the 75% percent rule applies. If the lateral length must exceed 75% then the system must be sized in accordance with the Category I venting tables.

Example 2:

Shows multiple offsets each at 45° degrees of inclination. Multiple offsets are permitted if they do not exceed 45° degrees of inclination. The total lengths of the two offsets are not required to meet the 75% percent rule.

Example 3:

Shows a single offset at 45° degrees of inclination and therefore the lateral length at 10 feet of offset does not have to meet the 75% percent allowable rule.

In each case the offsets must be supported and ﬁ restops must be positioned wherever the vent must pass through a sub-ﬂ oor, ceiling joist or an attic overhang. The vent pipe must terminate vertically into a listed type vent cap and extend a sufﬁ cient height through an approved roof ﬂ ashing, roof jack or a roof thimble. At all points the listed clearances must be maintained.

Vent terminations must be located in accordance with height and proximity rules of NFPA No. 54 or CAN/CSA B149. These rules apply to vents at 12 in. diameter or less and require a minimum height in accordance with the roof pitch and a minimum of 8 ft. distance from a vertical wall or obstruction (see Figure 11).

If venting horizontally through a side wall becomes necessary, a listed thimble approved for use with B-type vent must be used. Check with your local codes before venting through a side wall.

Some codes areas allow the use of existing B-type vent systems if the system is at or above the recommended diameter of the ﬂ ue.

The ﬂ ue connection must be made using listed B-type connectors and the existing system must be code inspected for damage and proper installation.

It is not recommended that this appliance be common vented with and existing gas burning appliance. However, if it becomes necessary to common vent the appliance. the venting system must be sized and conﬁ gured in accordance with the common venting guides Appendix G of the current

ANSI Z223.1

Note:

Before connecting this appliance to an existing vent system

and in Canada with

National Fuel Gas Code NFPA No. 54/

CHECKING FOR PROPER VENTING

After completing and checking the electrical, gas and vent connections, follow the lighting instructions and allow the main burner to run for approximately 5 minutes. Hold a match or butane lighter ﬂ ame, near the opening between the glass and the ﬁ replace face and play it along the entire length of the opening (Smoke may also be used). Proper venting will tend to draw ﬂ ame or smoke into the appliance. Improper venting, escaping or spillage of burned gas, is indicated when the match ﬂ ickers or goes out. See Figure 12. Smoke will also tend to disperse away from the appliance.

If the appliance is not venting properly, shut it off and notify your installer or a qualiﬁ ed service agency to inspect the venting system.

Check this area along the entire length of the fireplace opening. Smoke or flame should be drawn into the appliance opening.

When installing a non-high altitude ﬁ replace at an elevation above 2000 feet (610 m) (in the USA), you may need to decrease the input rating by changing the existing burner oriﬁ ce to a smaller size. Reduce input 4% for each 1000 feet (305 m) above sea level. Check with your local gas company for proper derate procedure and oriﬁ ce size.

When installing this ﬁ replace in Canada at an elevation above 4500 feet (1372 m), Check with local or provincial code authorities.

Consult your local gas company to help determine the proper oriﬁ ce for your location.
