Lochinvar F0600187510 Length of Air Inlet Pipe, Connecting the Air Inlet Pipe to the Pool Heater

Page 23

Installation and Service Manual

In cold climates, use a Type-B doublewall vent pipe or an insulated single wall pipe for combustion air. This will help prevent moisture in the cool incoming air from condensing and leaking from the inlet pipe.

￿CAUTION: Pool heaters that are shut down or will not operate may experience freezing due to convective airflow in the air inlet pipe.

Length of Air Inlet Pipe

The installed length of air inlet pipe from the pool heater to the outside air inlet cap must not exceed 50 equivalent feet (15.2m). Subtract 5 feet (1.5m) of equivalent length for each 90° elbow. Subtract 2.5 feet (0.7m) of equivalent length for each 45° elbow.

Do not exceed the limits for the combustion air inlet piping lengths.

Connecting the Air Inlet Pipe to the Pool Heater

Connect the air inlet piping directly to the pool heater by attaching it to the DV box adapter. The DV box adapter is included in the direct vent kits for horizontal direct vent. For vertical direct vent, order the DVK3003 kit from the pool heater manufacturer. The combustion air inlet area of the pool heater is located at the right rear corner of the pool heater. This pool heater uses a simple air filter to ensure clean air is used for the combustion process. Attach the DV box adapter over the air filter (see Figure 24). Align the screw holes on the DV box adapter with the screw holes surrounding the air filter hanger. Insert the sheet metal screws and tighten firmly.

Figure 24 – Attaching DV Box Adapter to Unit

For venting versatility, you can move the air filter assembly and DV box adapter to the right side of the pool heater. Remove the metal panel on the pool heater’s right side (see Figure 25). Remove the filter/bracket assembly from the rear of the pool heater.

Note: Modifications to the DV box adapter will be necessary to allow installation on the right side of the pool heater. Follow the instructions shipped with the vent kit.

Attach the filter/bracket assembly and DV box adapter to the right side opening using the pre-drilled screw holes. Make sure you attach the metal panel to the rear combustion air opening of the pool heater.

The DV box adapter has an air inlet pipe mounting ring. Connect combustion air inlet piping to the direct vent box mounting ring.

Air Inlet Piping Materials

The air inlet pipe(s) must be sealed. Select the air inlet pipe material from the following specified materials.

•PVC, CPVC, or ABS (6", 7", or 8" I.D.)

•Galvanized steel vent pipe with joints and seams sealed as specified below.

•Type-B doublewall vent with joints and seams sealed as specified below.

Check local codes for possible restrictions.

￿WARNING: Use only vent or air intake materials specified in this manual. Follow vent pipe manufacturer’s instructions. Failure to do so can result in property damage, personal injury, or death. Mixing of venting materials will void the warranty and certification of this pool heater.

Sealing Type-B Doublewall Vent Pipe or Galvanized Vent Pipe

Follow the steps below to properly seal Type-B doublewall vent pipe or galvanized vent pipe.

1.Seal all joints and seams of the air inlet pipe using either aluminum foil duct tape meeting UL Standard 723 or 181 A-P or a high quality UL Listed silicon sealant such as those manufactured by Dow Corning or General Electric.

2.On horizontal runs, do not install vent pipe with seams pointing down. Position vent pipe so that the seams are on the top side of the vent pipe.
