joints, including joining the pipe to the Termination (PVC Material). If local codes do not allow the use of the PVC termination when a material other than PVC is used for venting, then an equivalent fitting of that material may be substituted if the screen in the PVC terminal is removed and inserted into the new fitting.
PVC Materials should use ASTM
If the water heater is being installed as a replacement for an existing power vented heater in
NOTE: A. For water heaters in locations with high ambient temperatures (above 100°F) it is recommended that CPVC or ABS pipe and fittings be used. B. A 22.5 degree elbow (2" vent pipe) or a 45 degree elbow (3" and 4" vent pipe) with an installed screen VENT TERMINAL must be used in all cases.
4.There will be some installations where condensate will be formed in the horizontal runs of the vent system. This condensate will run into the condensate boot attached to the blower and out the fitting. The water heater is shipped with condensate hose that attaches to the fitting on the condensate boot. No other Tee or fitting is required. See Figures 5, 8 and 9.
CONDENSATE
WARNING
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 4) AND FROM TWO PLACES ON THE BLOWER ASSEMBLY (SEE FIGURE 5). 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.
NOTE: IT IS IMPORTANT THAT THE CONDENSATE HOSE ON THE BOTTOM OF THE UNIT IS NOT INSTALLED ELEVATED ABOVE THE CLAMP THAT IS SECURED TO THE SIDE OF THE JACKET, SEE FIGURE 4. THIS MUST BE TRUE FOR THE ENTIRE LENGTH OF THE HOSE FROM THE CLAMP TO THE EXIT INTO AN APPROPRIATE DRAIN. If these instructions are not followed or if the condensate hose is blocked, water will spill from the condensate trap. As with every water heater installation, a drain pan should be used to prevent water damage to the surrounding area. If necessary, a condensate pump with
an incorporated reservoir may be used to pump the water to an appropriate drain. To avoid condensate spillage, select a pump with an overflow switch.
CAUTION MUST BE USED TO ENSURE THAT THE DRAIN IS FREE AND CLEAR OF DEBRIS AND WILL NOT ALLOW BACKFLOW THROUGH THE CONDENSATE HOSE. 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.
The condensate trap may be primed by filling the CONDENSATE
IF THESE INSTRUCTIONS ARE NOT FOLLOWED, THE CONDENSATE
CONDENSATE SYSTEM - FIGURE 4
Condensate is likely to form in the venting system attached to this water heater. The vent pipe should be sloped downward away from the blower assembly (not less than 1/8" (3.2 mm) nor greater than 1/2" (12.7 mm) per foot maximum). If the vent piping is vented level or sloped upwards away from the blower assembly, then adequate means for draining and disposing of the condensate needs to be made by the installer. In either case, a 3/8" drain hose should be connected to the
PREPARATION OF BLOWER ASSEMBLY
1.Check to make sure that the wire harness is attached to the gas valve and blower control box.
2.Make sure no material is still attached to the outside or inside of blower assembly.
