When joining the various components of the above listed

vent systems, the manufacturers’ instructions should be

closely followed to insure proper sealing. Use sealant speci-

fied by vent system manufacturer for sealing of pipe and fit-

tings. See Figure 4 for proper application of vent pipe sealing

for Saf-T vent system by Heat-Fab, Inc. All vent connections

must be liquid and pressure tight. Flue vent system CANNOT

be cut to length. Consult manufacturer’s instructions. For Heat-

Fab system, use slip joint connector to adjust pipe lengths

dimensions.

DO NOT use plastic or galvanized flue pipe.

3” PVC Schedule 40 or galvanized steel materials are rec-

ommended.

All joints must be sealed using appropriate sealants.

1. Maximum allowed equivalent flue and air intake length for 

different flue systems at different altitudes are given in the

tables on page 7.

2. Equivalent of flue or air intake length is sum of the 

straight pipe lengths and equivalent length of elbows as 

shown in the table on this page.

3. The vent termination is in addition to the allowed equiva-

lent lengths.

4. Minimum flue length is 2 feet.

5. Flue length restriction is for both direct and non-direct 

vent installations.

EXAMPLE: Boiler model VSPH-180 is to be installed at sea

level. The combustion air is provided by air intake piping

directly to the boiler (direct-vent installation). Flue piping

includes 2 elbows and using Heat-Fab system. Air intake is

PVC and includes 3 elbows.

Maximum straight flue length would be 30-2x3=24 feet.

Maximum straight air intake pipe would be 40-3x5=25 feet.

If the air for combustion were taken from the boiler room

(non-direct vent installation), still the maximum straight flue

length would be 24 feet.

6.

All Victory VSPH boilers are equipped with a built-in 

condensation drain and trap. The trap loop must be 

filled with water. DO NOT operate the boiler without

filling the trap with water to prevent flue gas discharge 

into space. The drain should extend to a floor drain or 

to a container which may require emptying periodically.

7.

The horizontal vent pipe must be sloped upward from 

the boiler at a pitch of at least 

1

⁄

4

" per 1 foot of run, so 

that the condensate from the vent system runs to the 

drain trap.

8.

The horizontal vent pipes must be supported with pipe 

straps at intervals no greater than indicated by vent 

pipe manufacturer’s instructions. The vertical portion 

vent pipe also must be supported per manufacturer’s 

instructions. Support air intake piping in the same 

manner as the vent pipes.

9.

Minimum clearances of vent pipes from combustible 

constructions must be maintained (see Page 4). Main-

tain minimum 1" clearance between vent pipes and 

PVC air intake pipes.

10.

Common venting with other appliances or another 

VSPH boiler is not allowed.

11.

DO NOT install a vent damper or similar devices in 

vent system or on the boiler.

12.

Do not insulate venting system.
