All installations and services must be performed by qualified service personnel.

4.Measure the drain hose (11/16” o.d. clear tubing) provided and remove any extra length, making sure that the hose has sufficient length not to kink or otherwise be restricted once installed. Attach the drain hose (11/16” o.d. clear tubing) to the other side of the condensate trap tee. On CHX1/CDX1’s, this hose is shipped in the parts package and it will be necessary to attach the other end to the PVC drain tee assembly (see Figure 15). Use the silver clamp(s) provided in the parts package to secure all connections.

5.Install field supplied 1/2” CPVC drain pipe and elbows using CPVC cement to reach a nearby drain. A minimum 1/4” per foot downward slope toward the drain must be maintained. The drain line must be water tight, supported and secured so that it can’t be moved. The length of the drain must be kept as short as possible.

IMPORTANT: If an air conditioning condensate drain line is combined with the furnace condensate drain line, it must have a separate trap ahead of the joint connection.

6.If a drain is not readily available or is above the trap outlet level on the furnace or the drain line cannot be sloped downward its full length to the drain, then a condensate pump (part #350225) can be ordered from the factory. Follow the pump manufacturers installation instructions.

7.The furnace condensate is slightly acidic with a pH of 3.5. Cola drinks with a pH of 3.1 are actually more acidic. If local codes require a neutralizing kit, the kit may be ordered using part no. 320095. Instructions included with the neutralizing kit must be followed for its proper installation.

8.The condensate piping in the furnace and the drain system must be flushed out at the start of every heating season. This will assure trouble free operation and will keep the acidity level well above 3.4 pH.

To flush the condensate drain system, turn off power to the furnace at the electrical disconnect switch and turn the thermostat to the lowest setting.

Remove the 11/16” diameter clear tubing from the coil drain nipple and run tap water into the open end of the tubing. This should keep the drain system clean. Replace the tubing by pushing it firmly onto the nipple. Make sure the spring clamp is returned to the original position to prevent leaks. If any of the electrical controls are exposed to water, dry with a soft cloth and wait 24 hours before operating the furnace. Set the room thermostat to the desired temperature and restore electrical power to the furnace.

J. GENERAL GAS PIPING

: Because of the potential of odorant fade, a gas leak may not be detected by smell. If this furnace is installed below grade, contact your gas supplier for a gas detector.

1.Left and right gas supply piping - These furnaces are set-up to be gas piped through either the left or right side by using a street elbow and a straight pipe. For the purposes of service, it is recommended that the gas union be located inside the furnace, when possible.
