Wall Pass-Throughs

Whenever possible, design your installation so the con- nector does not pass through a combustible wall. If you must use a wall pass-through in your installation, check with your building inspector before you begin and con- struct it in accordance with local building codes. Also check with the chimney connector manufacturer for any specific requirements.

Accessories are available for use as wall pass- throughs. If using one of these, make sure it has been tested and listed for use as a wall pass-through. Figure 9 shows one method, in which all combustible material in the wall is cut away to provide the required 457 mm (18”) clearance for the connector. The resulting space must remain empty.

A flush-mounted sheet metal cover may be used on one side only. If covers must be used on both sides, each cover must be mounted on non-combustible spacers at least 25 mm (1”) clear of the wall. Your Dutchwest

dealer or your local building inspector can provide de- tails of other approved methods of passing a chimney connector through a combustible wall.

DO NOT CONNECT THE HEATER TO ANY AIR DIS- TRIBUTION DUCT OR SYSTEM.

Hearths

This appliance must be installed on to hearth that meets the requirements of Part J of the Building Regu- lations 2000 (Combustion Appliances and Fuel Storage Systems). This can be achieved by ensuring that the hearth is constructed and sized in accordance with the guidelines included in section 2 of approved document ‘J’. The size and clearances of the hearth are as fol- lows:

The constructed hearth should be constructed in ac- cordance with the recommendations in document J, and should be of minimum width 840 mm and minimum depth 840 mm (if a free standing hearth b) above) or a minimum projection of 150 mm from the jamb (if a recessed hearth a) above).
