Page 5: The Fireplace
THE FIREPLACE INTRODUCTION The BRENTWOOD fireplace is an energy efficient, heat circulating, close combustion fireplace. You will receive a lifetime of comfort and enjoyment from your fireplace provided it is installed, maintained and operated properly. • Please read these instructions and retain this manual for future reference. •... -
Page 6: Operating The Brentwood
OPERATING THE BRENTWOOD 3.2.1 Fuel The BRENTWOOD is designed to work best when fuelled with seasoned cordwood. Hardwoods are preferred to softwoods since the energy content of wood is relative to its density. Hardwoods will result in a longer burning fire and less frequent refuelling. A moisture content of 15% to 20% (seasoned) is recommended. -
Page 7: Primary Air And Air Boost Controls
3.2.4 Primary Air and Air Boost Controls There is no flue damper in the BRENTWOOD. As is common with air tight stoves, the combustion air control sets the flow of air entering the firebox. This allows for a more precise control of the fire. The combustion air control is located below the door on the left side. -
Page 8: Medium Combustion
3.2.6 Medium Combustion This is the recommended mode of operating the BRENTWOOD and should be the one normally used since it will deposit the least amount of creosote on the glass and in the chimney. The combustion air control must be 3/4 closed and pushed forward to close the air boost. -
Page 9: Smoking - Causes And Troubleshooting
3.2.9 Smoking – Causes and Troubleshooting To reduce the likelihood of smoking when opening the door, set the combustion air controls to the left before opening the door. Your fireplace has been designed and tested to provide smoke free operation. Occasionally, there may be a small amount of smoking upon lighting the fire, until the chimney heats up but this should not continue. -
Page 10: Important Notes
IMPORTANT NOTES A. Do not block the hot air vents to the fireplace as this will cause the fireplace to overheat. B. Never start a fire using gasoline, kerosene, charcoal lighter fluid or any other combustible liquid. C. Do not burn coal. The sulphur in coal will corrode the firebox. D. -

3.3.3 Top Baffle Removal Prior to Cleaning The Chimney Before starting to clean your chimney, we recommend that you remove the top baffle to avoid creosote dust collection at the top of the baffle. Follow these steps to set the top baffle out of the way: 1. -
Page 12: Door Adjustment
3.3.7 Refractory Replacement The intense heat of the fire will normally cause hairline cracks in the refractory. These cracks can be minimized by proper curing as described in "First Fires". They will not normally diminish the effectiveness of the refractory. If large cracks develop, then the refractory should be replaced. -
Page 13: Door Adjustment
3.3.9 Door Adjustment The door may need to be adjusted to be completely airtight. The gaskets’ air-tightness can be adjusted using the adjustment screw located on the right side of the fireplace façade. (An Allen key #1/8 – not supplied - will be necessary for this adjustment) 3.3.10 Glass Care - Replacement The glass used for the BRENTWOOD is a high temperature ceramic glass (1400°... -
Page 14: Fireplace Installation
FIREPLACE INSTALLATION 3.4.1 Locating The BRENTWOOD A. The best location to install your fireplace is determined by considering the location of windows, doors, and the traffic flow in the room where the fireplace is located, allowing space in front of the unit for the hearth extension and the mantel, and taking into consideration the location of the hot air ducts (optional), outside air kit and chimney. -
Page 15: Framing, Facing And Mantel
3.4.3 Framing, Facing And Mantel The construction of the framing, facing, and mantel must be in accordance with the standards and the following illustrations (figures 6 to 10): A. Frame the fireplace using 2" x 3" or heavier lumber. B. WARNING: Combustible materials cannot be used in the space directly above the fireplace, except for the studs above the facade that support the facing and mantel. -

INSULATED CHASE CONSTRUCTION Figure 10... - Page 17 Facing 1. Combustible material must be installed flush with the fireplace. It may not project in front of and on the fireplace (i.e. the steel façade of the fireplace) (figure 11). 2. Non-combustible materials such as brick, stone or ceramic tile may project in front of and onto the fireplace facing (figure 12).

Page 18: Hot Air Ducting Installation
HOT AIR DUCTING INSTALLATION Different hot air ducting systems can be installed with the BRENTWOOD: - Gravity kit Forced air kit 3.5.1 Gravity Kit Two kits are available: 1. Single hot air outlet including: (see Fig.13) - 2 6" lengths 8" I.D. - 1 hot air outlet kit (box, louver and frame) - 2 adaptors NOTE :... - Page 19 The single outlet system is designed to be installed either flush with the front of the BRENTWOOD or extended out slightly from the face of the fireplace (if installing with a brick or thick facing for example). To extend the double outlet system, it will be necessary to purchase two adjustable lengths (7B26ZL2A).
- Page 20 The duct system must be installed respecting the following: 1. Remove the plates closing up the 8" dia. holes on top of the fireplace. Then, cut the insulation in order to obtain two 8" dia. openings. Fix the adaptors on the fireplace openings by turning clockwise (figures 13 and 14).

Page 21: Outside Air Installation
OUTSIDE AIR KIT (Optional) During operation, the fireplace requires fresh air for combustion and draws air out of the house. It may starve other fuel burning appliances such as gas or oil furnaces. As well, exhaust fans may compete for air, causing negative pressure in the house, resulting in smoke entering the house from the fireplace. -
Page 22: Chimney Outside Air Kit Installation
AC CHIMNEY OUTSIDE AIR KIT (Optional) 3.6.2 * The outside air assembly for the AC (Air Cool) chimney is mandatory in some areas. Check with your local building authority for the requirements in your area. All required parts for outside air assembly are contained in the following kit: ACZIB 1) Install the outside air kit box and collar on the top of the unit. -
Page 23: The Chimney
THE CHIMNEY CHIMNEY INSTALLATION NOTES 1. Always install an interior chimney as it will provide better performance. In areas with continuous temperatures below -18° C (0° F), the use of an exterior chimney increases the likelihood of operating problems such as low draught, high rate of creosoting, and poor start-up characteristics. -
Page 24: Chimney Installation Instructions
CHIMNEY INSTALLATION INSTRUCTIONS 1. Cut and frame the holes in the ceiling, floor and roof where the chimney will pass (see figure 22). Use a plumb bob to line up the center of the holes. The sizes are indicated in table 1 for the floor and ceiling holes and table 2 (page 24) for the roof holes. - Page 25 AC CHIMNEY INSTALLATION (AIR COOLED GALVALUME CHIMNEY) Figure 24...

Page 29: Angled Wall Radiation Shield
ANGLED WALL RADIATION SHIELD (ACRSM30, ACRSMI30) When traversing a combustible wall with the chimney at a 30º, an angled firestop or wall radiation shield must be installed. Only one is required. In cold climate locations, we recommend that you use the insulated wall radiation shield since it will maintain the home’s thermal barrier. -
