minimum clearance from the vent to combustible materials when using
single-wall vent.
‡ Minimum 18-in. front clearance required for alcove.
NOTES:
1. Provide 30-in. front clearance for servicing. An open door in front of the
furnace can meet this requirement.
2. A minimum clearance of 3 in. must be provided in front of the furnace for
combustion air and proper operation.
3. Line contact is permitted as shown in Fig. 7.
Follow all safety codes. In the United States, follow all safety
codes including the National Fuel Gas Code (NFGC) NFPA No.
