Clearances to Combustibles
IMPORTANT: If unit is converted to an RDV33 from an RDV40,
the clearances to combustibles can be reduced as shown on
this page.
WARNING: If this unit is ever converted back to an RDV40,
ensure that the clearances are correct for this model.
Minimum Clearances to Combustibles
Minimum clearances include any projections such as shelves, window
sills, mantels, spacers/standoffs or surfaces to combustible construction
etc. above the appliance. Paint or lacquer used to finish the mantel
must be heat resistant in order to avoid discoloration.
The letters below, E through J, correspond to Figure 5 showing minimum
clearances required from the appliance to combustibles and the minimum
projection of the hearth extension.
