Installation instructions

Warning: Approved terminators must be used for inlet and exhaust vent systems to prevent rain from entering the appliance, failure to do so may result in damage to the appliance. This failure is not covered under the manufacturer’s warranty.

Open combustion installation (SINGLE PIPE SYSTEM)

Not recommended in cold climate areas, see chapter 3.4, page 15.

Connecting a one piece 90 degree elbow pipe to the combustion air inlet adaptor is required. This will prevent debris or objects from falling into the appliance.

The exhaust vent system must vent directly to the outside of the building and an adequate amount of indoor combustion air must be provided for this installation. See chapter 3.4.

Note: reduce 2.5 ft for each 90° elbow used after the

first one, reduce 1.25 ft for each 45° elbow.

A maximum of three 90-degree elbows are permitted.

Determining installation adjustment

The GWH 2400 ES comes factory set to accomodate most common venting arrangements. Determine the elbows and straight pipe you will require for exhaust and combustion air. Refer to the the table below to deter- mine if the factory setting for the fan is adequate. If your venting system is longer and exceeds the values listed in Table 8, proceed to Section 6.7, page 33 for fan speed adjustment.
