Installation guidelines:

Venting:

Must be 3" or 4" AL29-4C sealed stainless steel vent pipe. Slope horizontal runs up to termination ¼" per foot. The last horizontal section of exhaust vent pipe between last elbow and termination must slope down to the termination ¼" per foot. Do not combination vent with any other appliance.

Install condensate drain where applicable. See manual for vent terminator clearances.

Gas piping:

Heater will not function properly without adequate supply gas pressure.

Any appliance connector should be ¾" minimum diameter

Plumbing:

Install the included pressure relief valve and pipe to suitable drain.

Minimum piping diameter is ¾".

Do not solder directly to the bottom of the unit. Use unions to facilitate easy future maintenance. Use full port ball valves for isolation valves.

Partially fill condensate drain tube loop (where applicable) with water prior to start up.
