NOTE: The length of the bolt should not exceed 1-1/2 in.1. Lay furnace on its back. Locate and drill 5/16-in. diameterhole in each bottom corner of furnace as shown in Fig. 9.2. Install nut on bolt and install bolt with nut in hole. (Install flatwasher if desired.)3. Install another nut on other side of furnace base. (Install flatwasher if desired.)4. Adjust outside nut to provide desired height and tighten insidenut to secure arrangement.Step 6—Gas PipingEmissions control devices located at the heat exchanger inletsMUST be removed for propane installations (Refer to gasconversion kit for instructions).Gas piping must be installed in accordance with national and localcodes. Refer to the NFGC in U.S. Canadian installations must beinstalled in accordance with NSCNGPIC and all authorities havingjurisdiction.If a flexible connector is required or allowed by the authorityhaving jurisdiction, black iron pipe shall be installed at thefurnace gas control valve and extend a minimum of 2 in.outside the furnace casing. A failure to follow this warningcould result in fire, personal injury, or death.The gas supply line should be a separate line running directly fromthe gas meter to the furnace, if possible. Refer to Table 4 for therecommended gas pipe size. Risers must be used to connect to thefurnace and the meter.Piping should be pressure tested in accordance with local andnational plumbing and gas codes BEFORE the furnace has beenattached. If the test pressure exceeds 0.5 psig (14-in. wc), the gassupply pipe must be disconnected from the furnace and cappedbefore the pressure test. If the test pressure is equal to or less than0.5 psig (14-in. wc), close the manual shutoff valve before the test.(See Fig. 10.) It is recommended that the ground joint union beloosened before pressure testing. After all connections have beenmade, purge the lines and check for leakage with regulated gassupply pressure.Install a sediment trap in the riser leading to the furnace. The trapcan be installed by connecting a tee to the riser leading from thefurnace. Connect a capped nipple into the lower end of the tee. Thecapped nipple should extend below the level of the gas controls.(See Fig. 10.)Table 3—Filter Information (In.)FURNACECASING WIDTHFILTER SIZE* FILTERTYPESide Return Bottom Return14-3/16‡ (1) 16 X 25 X 1† (1) 14 X 25 X 1 Cleanable21 (1) 16 X 25 X 1 (1) 20 X 25 X 1† Cleanable24-1/2 (2) 16 X 25 X 1† (1) 24 X 25 X 1 Cleanable* Filters can be field modified by cutting the frame as marked and folding to thedesired size.
