Problems Causes/Solution
1. Inlet water pressure is erratic due to fluctuating supply water pressure. For
installation on the private well system with used of a pressure tank, the
lowest pressure range setting is 275 - 414 kPa. Consult your installer or
local plumber
Hot water temperature
fluctuates at tap
2. Set the temperature to a higher setting. This will allow you to use a higher
flow to hot water thus meeting the minimum flow requirement of 1.5 LPM
1. Make sure the combustion chamber is sealed. Leaky chamber may cause
the system to operates erratically
2. Improper venting. Venting that is unsealed or too long in run will result in
unstable burner flames and noises. Ensure venting is proper and in
accordance with specifications
3. Cross contaminations. Ensure that venting terminal is not partially blocked
or fully blocked. Cross contamination between intake and exhaust may
cause unstable burner flames and noise.
Noisy burner/unit during
operation
4. Fan does not work properly. Fan replacement may be required
White smoke comes out
of the exhaust
1. During colder weather when the exhaust temperature is much hotter than
the outside air, the exhaust fumes condense producing water vapor
