Clearances
These clearances apply to all dimensions except the framed opening,
where the clearance to combustibles is 0". The HW42DF clearance to
unprotectedcombustiblewallswhichareperpendiculartothereplace
opening, must not project beyond the shaded area shown in Fig. 24.
For protection against freezing temperatures, it is recommended that
outer walls of the chase be insulated with a vapor barrier. This will reduce
thepossibilityofacold-airconvectioncurrentonthereplace.
The HWDF Series clearances to combustible materials are:
