To avoid having too much flow at your faucets use the shut off valve after the mixing valve to limit the
overall flow of domestic hot water. Follow these instructions to achieve the best results with your Combi
boiler:
1. Open shut off valve fully.
2. Turn the dial on the mixing valve to the desired setting
(being careful not to exceed 120˚F or a
dial setting greater then 2)
and adjust LO setting accordingly.
3. Create the maximum amount of DHW flow that is likely to occur on a regular basis. (Usually tub
faucet, or choose two other faucets)
4. Allow the boiler to reach steady state, and then throttle the shut-off valve until the hot water
exiting the plate heat exchanger is warmer than the mixed water exiting the mixing valve. Ensure
the boiler is firing at the maximum rate, if not increase the LO setting and repeat this step. (It is
beneficial to keep the LO setting as low as possible to limit short cycling and maintain efficiency)
7.0 WIRING
All wiring must be in accordance with the Canadian Electrical code, CSA C22.2, and any applicable local
codes. Ensure that the wiring is in accordance with this manual.
Contact capacity of outputs C
1
or A
p
is 3 running Amps with a maximum inrush of 6
Amps.
If the capacity of the pumps is in excess of these maximums, you must either use a pump
controller, or isolation relay to energize the pumps.
