SAFETY RULES FOR OPERATING YOUR FIREPLACE • Use only an Osburn glass door, specifically designed for the model Osburn Stratford. • When cleaning the fireplace, the ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a non-combustible floor or on the ground outside the house, pending final disposal.

OPERATING THE OSBURN STRATFORD 3.2.1 Fuel The OSBURN STRATFORD 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.
3.2.4 Building a Fire To start a fire, place several crumpled up balls of newspaper in the firebox. Place small dry pieces of kindling on top of the paper, criss-crossing the kindling so that there are air spaces in between. Keep the fuel far back enough so that air can get underneath. Open the air controls fully and light the newspaper.
3.2.6 Primary Air There is no flue damper in the OSBURN STRATFORD. As in 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 right side.
Medium Combustion This is the recommended mode of operating the OSBURN STRATFORD 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 ¾ closed. The precise setting will depend on many factors, including chimney length and the moisture content of the wood.

C. Wet wood Wet or tarred wood will smoulder and smoke instead of burning properly. D. Dirty or blocked chimney Check to make sure the chimney is clear and clean. E. Chimney not long enough The minimum chimney height is 15 feet (4.6m). not including the fireplace’s height. The chimney must extend at least 3 feet (915 mm) above its point of contact with the roof and at least 2 feet (0.6 m) higher than any roof or wall within 10 feet (3 m) of it.
MAINTAINING YOUR OSBURN STRATFORD 3.3.1 Creosote When wood is burned slowly without a flame, it produces tar and other organic vapours which combine with expelled moisture to form a black deposit called creosote. Creosote accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire. If the creosote accumulation is large, a creosote fire in the chimney can damage the chimney and overheat the surrounding wood framing.
FRONT AIR TUBE Figure 2 3.3.4 Dealing with a Chimney Fire Regular chimney maintenance and inspection can prevent chimney fires. If you have a chimney fire, follow these steps: 1. Close the fireplace door and the combustion air controls; 2. Alert your family of the possible danger; 3.
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.

Let dry for at least 24 hours. To replace the glass gasket, simply remove the glass retainers holding the glass to the door frame.

FRESH 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.
THE CHIMNEY CHIMNEY INSTALLATION NOTES 1. If possible, 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.
CHIMNEY INSTALLATION INSTRUCTIONS 1. Cut and frame the holes in the ceiling, floor and roof where the chimney will pass (see figure 23). Use a plumb bob to line up the center of the holes. Make sure that the size of the floor and ceiling holes are in accordance with the chimney manufacturer’s instructions.

ANGLED WALL RADIATION SHIELD When passing through a combustible wall with the chimney at a 30° or 45° angle (30° or 45° in Canada and 30° only in the USA), an angled firestop or wall radiation shield provided by the chimney manufacturer must be installed.
CHIMNEY SUPPORT INSTALLATION Universal Roof Support This support has three possible uses: 1. It must be used on a roof to support the chimney. 2. It may be used on a floor, ceiling or roof above an offset to support the chimney above the offset.
4.7 INSTALLATION INSTRUCTIONS FOR MASONRY APPLICATION WARNING: Before starting the installation, the masonry chimney must be inspected by a qualified sweep. The following requirements must be respected: 1. The chimney must be absolutely clear of any soot residue or creosote. Check for cracks, loose or missing bricks that could inhibit correct installation of the liner.
