Figure 8: Typical Condensing System
Condensate from the MicoFlame must be treated before being discharged to drain. pH level of the
condensate is to be checked regularly and the neutralizing medium is to be replaced as required. A
neutralizing cartridge is available from the factory. The condensing MicoFlame must be vented using only
special venting type AL29-4C stainless steel or equivalent, please follow instructions detailed below.
When supplied with the CHRM, the MicoFlame is 95% efficient (category II or IV appliance) which
requires the use of a special venting system fabricated from AL29-4C or equivalent material. Only venting
components listed by a nationally recognized testing agency may be used.
This appliance may be installed with conventional, sidewall or vertical venting. Conventional vented
appliances operate with negative pressure in the vent pipe and require a special vent adapter to increase
the flue outlet diameter. Sidewall and vertically vented appliances operate with positive pressure in the
vent pipe and may be directly connected to the flue outlet without the use of an increaser.
Consult the vent pipe manufacturer’s instructions for minimum clearances to combustible material for vent
components. In the absence of instructions, the minimum clearance to combustible material is six inches.
Consult vent pipe manufacturer’s instructions for proper method of sealing vent pipe sections and fittings.
In the absence of instructions, make sure that pipe and fittings are clean by swabbing with alcohol. Use
Dow Corning 736 or 732 RTV, Polybar # 500 RTV or Sil-bond 4500 or 6500 to seal vent pipe. Do not use
other sealants or adhesives except as expressly permitted by vent manufacturer’s instructions.
Consult vent pipe manufacturer’s instructions for vent system assembly. Follow vent pipe manufacturer’s
instructions if those instructions differ from this section.
