TW2000 WOOD-FIRED BOILER – INSTRUCTION MANUAL

2.3Locating the Boiler

The location of the Boiler must be as close as possible to the tile-lined brick chimney, or factory-built solid-fuel approved chimney (ULC S629). Keep in mind also the day-to-day operation, and place for ease of fueling and cleaning.

To lighten the boiler for placement, all parts including firebrick and baffles can be removed.

It is important to provide adequate combustion air to the Boiler. It may be necessary to add a ventilator to an exterior wall of a closed Boiler room or an airtight basement.

The Boiler must be installed so that the clearances on page 13, or those of local authorities are met. If the Boiler must be installed on a combustible floor, a non- combustible base must be built as shown in Figure TW - 8. Two layers of hollow masonry block (4” thick) are placed at right angles to each other so that the ventilation holes of one layer are opposite to those of the other layer. Also for ember protection, there must be a minimum one layer of 26 ga. galvanized metal beneath the masonry blocks. This base must extend beyond the Boiler to a minimum distance of 18 in (457 mm) in front and 8 in. (204 mm) on all sides.

With the location of the boiler selected the next step is to position the unit and proceed with assembly. If a noncombustible base is not required Kerr recommends that the boiler be placed on masonry blocks (bricks or 8”concrete blocks) if space permits, to allow easier fueling and to keep the KERR TW2000 boiler above any possible water in the basement. These blocks should extend approximately 1” on all sides of the boiler to support the cabinet. Continue as follows:

1.Plan all plumbing and electrical runs so that flue pipe is easily removable for cleaning and to permit movement in the area as necessary.

2.Position masonry blocks and place the unit on top. Level the blocks as necessary.

3.Install the domestic coil if it is to be used, after removing the blank plate.

4.Set the loading door in place on the hinges.

5.Install aquastat wells, tridicator and pipe fittings using good quality pipe thread sealant or Teflon tape (Fig. TW-9).

6.Set each side panel in place with bottom of panel hooking over boiler base rail angle. Top fits down over sides and boiler. A perfect fit may be attained without any retaining screws.

7.Install the draft damper motor using the mounting holes provided, and connect the chain to the damper and to the damper motor wheel. Leave the bottom chain link open so that it may be disconnected in an emergency.
