3. APPLIANCE INSTALLATION 3.1 UNIT LOCATION The furnace must be installed where outsi de air supply is sufficient for prop er combustion. In airtig ht houses, it might be necessary to install an outside air inlet (see details in section 3.4). The furnace must be positioned so that the connec tor is as short as possible; minimize the use of 90 o elb[...]

3.3 PIPE CONNECTOR AND DAMPER Before proceeding to connection, remove all accessories such as scraper, shovel and poker from the evacuation pipe of the furnace. A 7” diameter chimney listed for use with wood burning hea ting appliances is highly recommended for the Hotblast 1950. In this case, a reduce r from 7” to 6” is required. If draft ex[...]

DAMPER The barometric control must be adjusted so that t he maximum draft measured at the furnace outlet is limited to - 0.06 in. w.c. Please note t hat a draft higher than -0.06 in. w.c. could result in an uncontrolla ble fire. On the other hand, the minimum draft to be respected is -0.0 4 in. w.c. in the evacuation pipe on the solid fuel side. 3.[...]
