Page 4 SL280UHV Gas Furnace The S L280UHV gas f urnace i s equipped with a t wo−stage, variable speed integrated control. the control is compat - ible with: Communicating thermostat s − icomfort T ouch ® . Non−comunicating thermostat s − ComfortSense or other conventional thermostat s.
Page 5 T emperature Rise NOTE − Furnace must be adjusted to obtain a temperature rise(high a nd l ow f ire) within the r ange(s) s pecified o n the unit nameplate. Failure to d o so m ay cause erratic limit o peration and may result in premature heat exchanger failure.
Page 6 Place the furnace as close to the center of the air dis- tribution system as possible. The furnace should also be located close to the chimney or vent termination point. Do not install the f urnace where drafts might blow direct- ly into it.
Page 7 Unconfined Sp ace An unconfined space is an area such as a basement or large equipment room with a volume greater than 50 cubic feet (1.42 m 3 ) per 1,000 Btu (.29 kW) per hour of the com- bined input rating of all appliances installed in that space.
Page 8 EQUIPMENT IN CONFINED SP ACE ALL AIR FROM OUTSIDE (Inlet Air from Crawlspace and Outlet Air to V entilated Attic) NOTE−The inlet and outlet air openings shall each have a free area of at least one square inch (645 mm 2 ) per 4,000 Btu (1.17 kW) per hour of the tot al input rating of all equipment in the enclosure.
Page 9 Setting Equipment W ARNING Do not inst all the furnace on its front or it s back. Do no t connect the return ai r ducts to the back of the fur- nace. Doing so will adversely affect the operation of the safety control devices, which could result in per- sonal injury or death.
Page 10 Return Air −− Up flow Applications Return air can be brought in through the b ottom or either side o f the furnace installed in an upflow a pplication.

Page 22 Removal of the Furnace from Common V ent In the event that an existing furnace is removed from a venting system commonly run with separate gas ap- pliances, the venting system is likely to be too large to properly vent the remaining attached appliances.
Page 23 Gas Piping CAUTION If a flexible gas connector is required or allowed by the authority that has jurisdiction, black iron pipe shall be in st alled at the gas valve and extend out side the furnace cabinet. The flexible connector can then be added between the black iron pipe and the gas supply line.
