Never use this water heater unless it is completely full of water. To prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” gas to the water heater.

To fill the water heater with water:

1.Close the water heater drain valve by turning handle to the right

(clockwise). The drain valve is on the lower front of water heater.

2.Open the cold water supply valve to the water heater.

NOTE: The cold water supply valve must be left open when the water heater is in use.

3.To insure complete filling of the tank, allow air to exit by opening nearest hot water faucet. Allow water to run until a constant flow is obtained.

This will let air out of the water heater and the piping.

4.Check all water piping and connections for leaks. Repair as needed.

VENT PIPE ASSEMBLY

There are three parts of the vent pipe assembly that connect the water heater exhaust (located on lower back side of water heater) to inlet of the blower assembly (mounted on top of water heater) as shown in Figure 1. These parts will need to be assembled according to these instructions.

Assemble Vent Pipe Assemblies #1, #2 and #3 (See Figure 1) prior

to cementing. The preferred orientation of Vent Pipe Assembly #1

(Condensate U-Assembly) is shown in Figure 16. However this

assembly may be rotated to a different orientation as needed for the

specific installation requirements. Note the rotational orientation of

each part by marking a line several inches long across the joints.The long tube of Vent Pipe Assembly #2 should be approximately vertical. If it is found that either of the two pieces of pipe in Vent Pipe Assembly

#2 are too long for proper fit-up, then remove as little material as possible to improve the fit-up. Keep in mind that the pipes will insert

slightly further into the elbows when cement is applied as it acts as a lubricating agent. The vertical distance from the bottom of the

Condensate U-Assembly to the floor that supports the water heater

should be approximately 0.25” (0.64 cm), see Figure 16. Disassemble the parts and cement back together using the alignment marks. After the cement dries, attach the assembly to the blower and the water heater exhaust using the supplied rubber boots and hose clamps.

Acondensate trap is incorporated in the bottom of this vent pipe assembly. See the CONDENSATE section of this manual for further details.
