Cement and primer must comply with ASTM D2564 or F493. For Canada, use CSA or ULC certified PVC or CPVC pipe, fittings and cement, see table 5. PP pipe must be certified under ULC S636. Appliance condensate drain installation The appliance comes equipped with an internal condensate drain and siphon.
Installation instructions Installation For this solution to be effective, the internal flapper must be 100% closed when the water heater is not running. Refer to Figures 23 and24 for preferred installation positions in the vent system. Installation considerations: • Install damper per the supplied manufacturer‘s instructions. • The damper is only to be used in the exhaust vent piping. • Ensure directional arrow on damper label faces in the same direction as exhaust flow.
Installation instructions 4.3.7 Common venting of 2 to 4 units 2 to 4 unit cascades can be common vented using the optional PP common venting system. The water heaters can be installed in a back to back configuration as shown in fig. 26, or side by side as shown in fig. 27. The systems are custom configurable for vent lengths from 40” (1m) up to 100’ (30m) and either a vertical or horizontal termination (see fig. 25).
Installation instructions 4.3.8 Fan speed adjustment necessary adjustments to fan speed values may result in improper operation of the appliance. NOTICE: IMPORTANT INFORMATION! ▶ Natural gas heaters with installation altitudes below 2,000 ft above sea level disregard this section. Installation adjustment: After installing the tankless water heater, the fan speed values for minimum power (P2) and maximum power (P1) may need adjustment due to variations in altitude and vent pipe length.

Maintenance and service 7.2 Winterizing for seasonal use The water heater must not be installed in a location where it may be exposed to freezing temperatures. If the heater must be left in a space which is likely to experience freezing temperatures, all water must be drained from the heater. If precautions are not taken, resulting damage will not be covered under the warranty.
Maintenance and service ▶ Dismantle all parts for inspection and cleaning. ▶ Insert CO2 analyzer probe into the measuring port. The tip of the probe should be in the center of the flue pipe (approx 1.5" inserted). Avoid air gaps between probe and measuring port as they can alter readings.

Troubleshooting 7. Check for plumbing crossover. A crossover in the hot and cold plumbing pipes creates back pressure on the water flowing through the heater. Therefore, a higher flow rate than normal is needed to force the heater to activate. To check for a plumbing crossover, shut off the cold water supply to the water heater. Then open all of the hot water taps served by the heater. Wait 10 minutes and check for water flow at each tap. There should be no water flowing.
Problem solving 8.7 Noisy burner/heater during operation 1. Sealed combustion leak. Make sure combustion cover is securely fastened. Ensure the exhaust vent adaptor is properly sealed with supplied gasket. Leaky seals create improper combustion resulting in noise. 2. Improper venting. Venting that is unsealed, the wrong material, too big in diameter or too long in run will result in unstable burner flames and noise. Ensure venting is in accordance with specifications in chapter4.3, page 10. 3.
Problem solving Display C6 Cause Primary fan rotation too low in operation. C7 (Flashing) CA E1 E2 E3 E4 E9 Solution 1. Disconnect power supply cord and check wire connection on back side of fan and the connectors on the control board. 2. Check supply voltage. It must be 120VAC and properly grounded. 3. Check venting specifications are met. Long vent lengths, venting with more than three elbows, blocked vent or combination venting may cause this failure. 4.
