Maximum input is 26,000 BTU/hr for natural gas and propane for the GD36. Maximum input for the BGD36 is 17,000 BTU/h for natural gas and propane. When the fireplace is installed at elevations above 4,500ft, and in the absence of specific recommendations from the local authority having jurisdiction, the certified high altitude input rating shall be reduced at the rate of 4% for each additional 1,000ft.

GD36

Maximum output for natural gas is 22,360 BTU/hr at an efficiency of 86% with the fan on, and 22,880 BTU/hr for propane at an efficiency of 88% with the fan on. The A.F.U.E. (annual fuel utilization efficiency) rating is 64% for natural gas and 65% for propane.

BGD36

Maximum output for natural gas and propane is 10,900 BTU/ hr at an efficiency of 64% with the fan on. The A.F.U.E. (annual fuel utilization efficiency) rating is 53% for natural gas and propane.

Minimum inlet gas supply pressure is 4.5 inches water column for natural gas and 11 inches water column for propane. Maximum inlet gas pressure is 7 inches water column for natural gas and 13 inches water column for propane. Manifold pressure under flow conditions is 3.5 inches water column for natural gas and 10 inches water column for propane. This fireplace is approved for bathroom, bedroom and bedsitting room installations and is suitable for mobile home installation.

No external electricity (110 volts or 24 volts) is required for the gas system operation.

Expansion / contraction noises during heating up and cooling down cycles are normal and are to be expected.

CARE OF GLASS, AND PLATED PARTS

Do not use abrasive cleaners to clean plated parts. Buff lightly with a clean dry cloth. The GD36 is factory equipped with ceramic glass. The BGD36 is factory equipped with tempered glass. The glass thickness is 3/16" for both models. Use only replacement glass available from your Napoleon dealer. DO NOT SUBSTITUTE MATERIALS. Clean the glass after the first 10 hours of operation with a recommended gas fireplace glass cleaner. Thereafter clean as required. DO NOT CLEAN GLASS WHEN HOT! If the glass is not kept clean permanent discolouration and / or blemishes may result.

Use only accessories designed for and listed with your specific fireplace.

Provide adequate ventilation air. Provide adequate accessibility clearance for servicing and operating the fireplace. Never obstruct the front opening of the fireplace.

For safe and proper operation of the fireplace follow the venting instruction exactly.

Deviation from the minimum vertical vent length can create difficulty in burner start-up and/or carboning. Provide a means for visually checking the vent connection to the fireplace after the fireplace is installed. Vent lengths that pass through unheated spaces (attics, garages, crawl spaces) should be insulated with the insulation wrapped in a protective sleeve to minimize condensation.

Objects placed in front of the fireplace must be kept a minimum of 48" away from the front face of the unit.

VENTING

MODELS GD36 AND BGD36 MAY BE VENTED EITHER AS A TOP VENT OR A REAR VENT.

REFER TO THE SECTION APPLICABLE TO YOUR INSTALLATION.

VENTING LENGTHS

Use only Wolf Steel or Simpson Dura-Vent Model DV-GS venting components. Minimum and maximum vent lengths, for both horizontal and vertical installations, and air terminal locations for either system are set out in this manual and must be adhered to. For Simpson Dura-Vent, follow the installation procedure provided with the venting components.

When using Wolf Steel venting components, use only approved Wolf Steel rigid / flexible components with the following termination kits: WALL TERMINAL KIT GD222, or 1/12 TO 7/12 PITCH ROOF TERMINAL KIT GD110, 8/12 TO 12/12 ROOF TERMINAL KIT GD111, FLAT ROOF TERMINAL KIT GD112 or PERISCOPE KIT GD201 (for wall penetration below grade). With flexible venting, in conjunction with the various terminations, use either the 5 foot vent kit GD220 or the 10 foot vent kit GD330.

Wolf Steel rigid and flexible venting systems must not be combined.

Wolf Steel and Simpson Dura-Vent venting systems must not be combined.

These vent kits allow for either horizontal or vertical venting of the fireplace. FIGURES 3 & 5. The maximum allowable horizontal run is 20 feet. The maximum allowable vertical vent length is 40 feet. The maximum number of 4" vent connections is two horizontally or three vertically (excluding the fireplace and the air terminal connections) when using aluminum flexible venting.

For optimum flame appearance and fireplace performance, keep the vent length and number of elbows to a minimum.

The air terminal must remain unobstructed at all times. Examine the air terminal at least once a year to verify that it is unobstructed and undamaged.

Purge all gas lines with the glass door of the fireplace open. Assure that a continuous gas flow is at the burner before closing the door.

Under extreme vent configurations, allow several minutes (5-15) for the flame to stabilize after ignition.

Six (6") inches is the minimum bend radius allowed for the 7" diameter flexible liner.

For optimum performance it is recommended that all horizontal runs have a 1 inch rise per foot when using Napoleon flexible vent components.

A terminal shall not terminate directly above a sidewalk or paved driveway which is located between two single family dwellings and serves both dwellings. Local codes or regulations may require different clearances. Do not allow the inside liner to bunch up on horizontal or vertical runs and elbows. Keep it pulled tight. A 1¼" air gap all around between the inner liner and outer liner is required for safe operation. Use a firestop when penetrating interior walls, floor or ceiling.

Minimum clearance to combustible construction from fireplace and vent surfaces:

sides, back, bottom and top of the unit

0 inch

recessed depth

14 inches

top, sides and bottom of the vent pipe*

1 inch

top of the vent pipe - rear vent only*

2 inches

* REAR VENT - A clearance to combustibles of 1" at the bottom of the vent and 2" at the top must be maintained during the first 12" of venting when penetrating combustible walls. The firestop spacer (W615-044) supplied with the unit should be used to maintain this clearance. Thereafter a 1" clearance to combustibles may be maintained using firestop spacer (W500-0096).

TOP VENT - Only a clearance to combustibles of 1" all around the vent pipe is required.

For optimum performance, it is recommended that all horizontal runs have a 1 inch rise per foot.

When terminating vertically, the vertical rise is a minimum 36 inches and a maximum 40 feet from the centre of the fireplace flue outlet.

* When using rigid venting, this minimum vertical length may be reduced to 8½".

SPECIAL VENT INSTALLATIONS

PERISCOPE TERMINATION

CORNER TERMINATION

Use the GD201 periscope kit to locate the air termination above grade. The periscope must be installed so that when final grading is completed, the bottom air slot is located a minimum of 12 inches above grade. The maximum allowable vent length depends on the model of fireplace, as illustrated.

FIGURES 4

MODELS GD36: The maximum vent length for a corner installation is 24 inches, where only 6 inches of vertical rise is used. All corner installations require a minimum 6 inch rise. See FIGURE 5A.

MODELS BGD36: The maximum vent length for a corner installation is 20 inches of horizontal run, in addition to the 45° offset. In this case zero rise is acceptable when using rigid. Flexible venting must maintain a 6" rise. See FIGURE 5B.
