Camus Hydronics MFH060 Installation, Operation And Service Manual page 22

A neutralizer cartridge is provided and must be installed in the line from the condensate collection pot to
the drain. pH level of the condensate is to be checked regularly and neutralizing medium is to be replaced
as required to maintain effectiveness. A neutralizer cartridge is available from the factory.
CONDENSING HEAT RECOVERY MODULE PIPING CONFIGURATIONS
Caution: If isolation valves are provided on the CHRM, the provision of a relief valve at the outlet of the
secondary is recommended. This valve is to be sized at minimum for 10% of the input of the appliance
and is to be piped to drain in a manner similar to the appliance relief valve.
CHRM IN SERIES WITH PRIMARY HEAT EXCHANGER (INTEGRATED LOOP)
The MicoFlame could be provided in condensing mode for a variety of application including domestic hot
water and hydronic space heating.
The CHRM is intended to extract total (sensible and latent) heat from the flue gases downstream of the
primary heat exchanger. As a result, condensation of moisture in the flue gas will take place on the
CHRM surfaces and in the exhaust vent. This condensation is a natural outcome when efficiencies
exceed 90%.
Recommended installation methods of the condensing MicoFlame will vary depending on the application
and the expected water temperature variation of the system.
Examples of recommended installation for typical applications are shown on the next page:
