CONDENSATE

This water heater is a condensing unit and requires a drain to be located in close proximity to allow the condensate to drain safely. The condensate drains from the unit at the exhaust tee located at the bottom of the unit (see Figure 22). Condensate from this water heater is mildly acidic. Please note that some local codes require that condensate is treated by using a pH neutralizing filter prior to disposal.

Caution must be used to ensure that the drain is free and clear of debris and will not allow backflow through the condensate tube. Consideration must be given to avoid freezing of the condensate lines which could result in excessive build up of condensate inside the water heater. Waterproof heat tape may be required to prevent freezing of the condensate lines. Please ensure that the outlet of the condensate drain does not create a slippery condition which could lead to personal injury.

To operate properly and prevent exhaust gases from escaping through the condensate trap, the trap must contain some water. Before being started for the first time, water must be added to the trap. Remove the condensate tube (if installed) and add water to the trap through the hole for the condensate tube until it flows from the hole. (Re)install the condensate tube.

CONDENSATION WARNING:

THIS WATER HEATER IS A CONDENSING UNIT AND REQUIRES A DRAIN TO BE LOCATED IN CLOSE PROXIMITY TO ALLOW CONDENSATE TO DRAIN SAFELY. THE CONDENSATE DRAINS FROM UNIT AT THE EXHAUST ELBOW LOCATED AT BOTTOM OF UNIT.

NOTE: IT IS IMPORTANT THAT THE CONDENSATE TUBE NOT BE ELEVATED ABOVE THE CONDENSATE TRAP OUTLET (SEE FIGURE 22). CONDENSATE BUILD-UP WILL BLOCK THE EXHAUST OUTLET, WHICH WILL CAUSE IMPROPER OPERATION. WITH SOME INSTALLATIONS IT IS RECOMMEND TO INSTALL A CONDENSATE PUMP.

NOTE: Barbed fitting not required if hard piping is used to drain condensate.

INSTALLATION OF VENT SYSTEM

Before beginning installation of piping system thoroughly read the “Vent Pipe Preparation” section of this manual.

If you are installing your system so that it vents through roof, please refer to the section titled “Installation Of Vertical Vent System”.

Ensure the vent length is long enough that the outside air will not cause the water heater to freeze.

VENT TERMINAL INSTALLATION, SIDEWALL

1.Install the vent terminal by using the cover plate as a template to mark the hole for the vent pipe to pass through the wall. BEWARE OF CONCEALED WIRING AND PIPING INSIDE THE WALL.

2.If the Vent Terminal is being installed on the outside of a finished wall, it may be easier to mark both the inside and outside wall. Align the holes by drilling a hole through the center of the template from the inside through to the outside. The template can now be positioned on the outside wall using the drilled hole as a centering point for the template.

3.A) MASONRY SIDE WALLS

Chisel an opening approximately 1/2 in. (1.3cm) larger than the marked circle.

B)WOODEN SIDE WALLS

Drill a pilot hole approximately 1/4 in. (0.64cm) outside of the marked circle. This pilot hole is used as a starting point for a saws-all or sabre saw blade. Cut around the marked circle staying approximately 1/4 in. (0.64cm) outside of the line. (This will allow the vent to easily slide through the opening. The resulting gap will be covered up by the Vent Terminal cover plate.) Repeat this step on inside wall if necessary.
