CONDENSATE DRAIN

If the condensate pump is installed, is it wired to deactivate the tankless water
heater in the event of failure? For more information, refer to section "4.9.3
Condensate Pump Safety Switch Wiring."
Did you verify the condensate drain pipe is as short as possible and has a downward
pitch toward the drain or condensate pump?
Is all condensate drained and disposed of as per local codes?
Did you use ONLY corrosion resistant materials for the condensate drain lines?
Did you verify the condensate drain pipe along its entire length is at least the
same diameter as the drain line (1/2 in. NPT)?
Did you check to ensure the condensation drain lines are protected from freezing?
If a floor pump is not available or the drain is above the level of the condensate
drain, did you install a condensate pump?
Have you verified the condensate drain line is not plumbed with the pressure relief
valve?
Have you confirmed the condensate drain line is not connected with an air
conditioning evaporator coil drain?
Have you verified an external condensate trap is not installed? (This tankless water
heater has an integrated condensate trap.)
Have you confirmed the end of the condensate drain pipe is open to atmosphere?

GAS SUPPLY

Did you verify the gas system is appropriately sized?
Did you verify the water heater is rated for the gas type supplied?
Have you performed a gas line and connection leak test?
Did you install a manual gas control valve in the gas line to the water heater?
Is the inlet gas pressure within limits?
Did you purge the gas line of any air or debris before connecting the water heater?
If "LPG" (Liquid Propane Gas) is selected, apply the supplied gas conversion label at
an open space above the existing label on the side of the water heater.
8 RECIRCULATION PUMP CXP Series Models Only (CXP199i and CXP160i)
Have parameter settings for recirculation been properly set?
Is the recirculation pipe length less than the maximum allowed length?
Did you drain the tankless water heater if not intended to be used immediately?
Have you performed a leak and pressure test on the thermal bypass valve installation?
(Crossover Mode Only) Was the thermal bypass valve installed at the furthest fixture
from the water heater?
