When installing the adaptor rubber boot, note the following:
• 

Remove and discard the plastic cap from the outer 

clamshell housing (see figure 4A).

• 

To connect the heater to the air inlet, use the vent 

adaptor rubber boot provided in the base skirt. The 

adaptor rubber boot is designed for 3” venting (see 

figure 4B). Note: If there is a need for 2” venting, then 

use plastic pipe and fittings to transition down.

• 

Loosen the hose clamp at the adaptor rubber boot and 

slide the plastic piping into the adaptor rubber boot. 

With piping in place, tighten the hose clamp. Install  a 

3” x 3” x 3” TY drain/waste/vent fitting to trap airborne 

particulates (see figure 4C). Note: If piping has been 

previously cut with a saw, be sure to remove all burrs 

and plastic shavings from the piping before installing.

The heater is designed to shut down if the pressure 

switch senses that the air inlet vent or the exhaust vent 

is restricted. In this case, the pressure switch will open 

and the heater will generate a 2-flash code (see the 

troubleshooting section). If troubleshooting section of 

this manual indicates that there is a blockage, note the 

following:
• 

Turn off the gas supply to the water heater at the 

manual gas shut-off valve, and disconnect power to the 

water heater.

• 

To inspect the filter, loosen the hose clamp at the adap-

tor rubber boot and slide the plastic pipe out and away 

from the adaptor rubber boot (see figure 4C).

• 

Remove the adaptor rubber boot containing the outer 

clamshell housing by turning clockwise approximately 

1/2” (30.5 cm) and pulling off of the internal clamshell 

housing (see figure 4C).

• 

Using your fingers or a small flat blade screwdriver,   

remove the filter media from the outer clamshell hous-

ing, handle carefully (see figure 4D).

• 

To clean filter, lightly tap the back of the filter support 

to dislodge any large debris. Smaller debris may be re-

moved by using a vacuum cleaner. the filter media may 

be cleaned by dipping the filter media into a solution of 

warm soapy water and rinsing in clean water. Do not 

scrub, allow to air dry before reinstalling. Filter media 

may be cleaned on an average 2 to 3 times before 

replacing with a new filter media is required.

• 

Reinstall the filter media by doing the above steps in 

reverse order.

• 

Turn on the gas supply and reconnect power, refer to 

the operating instructions on front of the water heater. 

Verify proper operation of the water heater before   

leaving.
