VENTING OF THE A232 FIREPLACE

Note: Please refer to installation instructions supplied by chimney manufacturer prior to commencing installation.

The A232 may be installed using 4" diameter single wall vent up to an existing masonry chimney.(Fig. 14) This vent should then be connected to a 4" liner running the full height of the chimney, as it is mandatory in most jurisdictions that the chimney be lined.

Another option is 4" "B" vent directly off the fireplace (Fig.13 & 11), going up to the chimney liner or up through the roof if no chimney exists.

A minimum 12 foot vent height is required to effectively vent this fireplace.

COMMON FLUE INSTALLATIONS

In some areas it is possible to vent more than one gas fireplace into the same flue. You must ensure that the flue being shared has the proper capacity to handle both fireplaces. Check installation codes for venting capacity information.

As always it is best to check with the authority having jurisdiction prior to commencement of the installation.
