For installations above 5,500 feet use only direct vent (ducted combustion  
air) when sidewall venting. All of the vertical (through-roof or through-  
unused-chimney) methods in thisVenting Supplement are acceptable. Can  
result in severe personal injury, death or substantial property damage if  
ignored.

anticipated snow line. In addition, vent termination must be  
at least 7 feet above public walkway and 3 feet above any forced  
air intake within 10 feet. Stay well away from trees, shrubs,  
and decorative items. Site conditions may dictate greater  
clearances. See Figure 1.  
Venting method definitions  
Direct vent — Uses outside combustion air with combustion  
air connector piping sealed at all joints and seams.Also known as  
“sealed combustion.  
Non-Direct vent — Uses inside combustion air with no  
9. Vent must terminate at least 4 feet horizontally, and in no  
case above or below, unless a 4 foot horizontal distance is  
maintained, from electric meters, gas meters,regulators, relief  
valves, and other equipment.  
10. Locate or guard vent to prevent condensate from damaging  
exterior finishes.  
11. Do not extend exposed vent pipe outside of building.  
Condensate could freeze and block vent pipe.  
12. Vent must terminate at least 6 feet away from adjacent walls.  
13. Do not terminate vent closer than 5 feet below roof overhang.  
combustion air connector piping.  
Properly locate vent termination  
Follow instructions on this page when  
determining vent location to avoid possibility  
of severe personal injury,death or substantial  
property damage.  
1. When using direct vent method — Refer to separate  
instructions packed with Weil-McLain direct vent termination  
kit and vent pipe manufacturer's instructions for additional  
locations.  
2. For location of non-direct vent vertical termination, see vent  
pipe manufacturer's instructions.  
3. Gases will form white plume in winter.Plume could obstruct  
window view.  
4. Prevailing winds could cause freezing of condensate and  
water/ice buildup on building, plants or roof.  
5. Locate or guard vent to prevent accidental contact by people  
or pets.  
6. Do not terminate vent in window well, stairwell, alcove,  
courtyard, or other recessed areas.  
7. Non-Direct vent installations only — Vent must terminate  
more than 1 foot below or to side of all doors or windows.  
See Figure 1.  
14. Do not terminate vent above any door or window.Condensate  
can freeze, causing ice formations.  
15. Do not use existing chimney as raceway if another appliance  
or fireplace is vented into or through chimney.  
16. Do not connect:  
Any other appliance to vent pipe.  
Multiple boilers to a common vent pipe.  
17. Do not wrap or insulate vent pipe and fittings.  
18. Canadian installations — See CAN/CGA B149.1 or B149.2  
Installation Code.  
19.  
A gas vent extending through an exterior  
wall shall not terminate adjacent to the wall  
or below building extensions such as eaves,  
parapets, balconies or decks. Failure to  
comply could result in severe personal  
injury, death or substantial property  
damage.  
8. Vent must terminate more than 1 foot above grade or

Installation  
Pre-installation planning  
1. Follow national, state, local or provincial codes or  
regulations when venting GV boiler.  
2. Choose vent method from those shown on page 5.  
3. Select vent run components from Table 2. Table 3  
states maximum vent run lengths and number of  
elbows.Do not exceed data in Table 3. Longer vent  
runs will slightly reduce boiler output. See Figure 2.  
4. If installing with direct vent method, use same  
maximum run length and number of elbows from  
step 2. Vent and combustion air connector piping  
configurations must match.Use suitable 3" material  
for combustion air connector piping, such as:  
Dryer vent  
Galvanized steel  
PVC (3" I.D.)  
5. Refer to vent termination WARNING, item 19 on  
page 3.

Installation — assembly  
Connect vent starter  
tee to boiler  
Follow the instructions in the GV Series 3 Boiler Manual section IIb to connect the vent  
starter tee to the boiler.  
Follow vent pipe manufacturer's instructions for sealing the vent.Vent and  
combustion air connector piping must be sealed gas-tight to prevent  
possibility of flue gas spillage and carbon monoxide emissions, resulting in  
severe personal injury or death.  
Construct vent and  
optional  
combustion air run  
1. Follow StaR-34 manufacturer's instructions to construct vent run and for methods of  
supporting vent runs.  
Clean joints before sealing. See vent pipe manufacturer's instructions to clean joints.  
Use their specified sealant (maximum 250 0F flue temperature). Do not use screws.  
Do not mix types or manufacturers of vent materials.  
Maintain minimum one-inch clearance from combustible materials to vent pipe; 0"  
clearance for noncombustible materials.  
Install vent pipe with seams on top of vent runs.  
If needed, male end of vent pipe may be cut to provide correct length. See vent pipe  
manufacturer's instructions for use.  
2. If installing with direct vent method, use instructions provided with Weil-McLain  
termination kit. See Figures 3, 4 or 5 on page 5.

Connect vent run to  
termination  
1. If using Weil-McLain Vent/Air Intake Termination Kit, see instructions provided in that  
kit. Applies to direct (Figure 3, page 5) or non-direct vent (Figure 4, page 5) method.  
2. If using non-direct method with termination coupling only, see Figures 8 and 9.  
If passing through noncombustible wall, provide hole diameter large enough to insert  
the pipe through. Sleeve and spacers are not required.  
3. Maintain minimum one-inch clearance from combustible materials to vent pipe; 0"  
clearance for noncombustible materials.  
4. Refer to vent termination WARNING, item 19 on page 3.

1. Direct vent method — follow instructions supplied in Weil-McLain Through-Roof or  
Through-Unused-Chimney Termination Kit to assemble termination.  
2. Non-Direct vent method (only through the roof, not through chimney):  
Vent pipe must extend through roof flashing, jacket or thimble. See Figure 10.  
Vent may pass through floor, inside wall or concealed space when installed according  
to vent pipe manufacturer's instructions.  
3. Maintain minimum one-inch clearance from combustible materials to vent pipe.

When vent pipe or combustion air pipe is disconnected for any reason, it must be reassembled  
and resealed according to thisVenting Supplement,the direct vent termination kit instructions  
and the vent pipe manufacturer's instructions.  
Sealant recommended by vent pipe manufacturer must be used as indicated  
in their instructions. Vent and combustion air connector piping must be
