V. Venting (continued)
6. Install Vent Terminal. See Figure 14.
a. Locate roof opening to allow vertical vent
penetration. Size opening to maintain minimum
clearance from combustible materials.
b. Installroofashing.
c. Extend vent pipe to maintain minimum height
[H]aboveroofasspeciedinTable9.Vent
terminal must be minimum 2 feet horizontally
from roof surface and minimum 8 feet from any
vertical wall or similar obstruction. Provide
bracing as required in Table 9.
d. Install storm collar on vent pipe immediately
aboveashing.Applysealantbetweenventpipe
and storm collar.
e. Attach Vent Terminal.
7. Install condensate drain line. Use 3/8 inch i.d. high
temperatureexibletubingsuchassiliconerubber
or EPDM. See Figure 12.
a. Form condensate trap with 6 inch diameter loop.
Secure loop with plastic cable tie. Fill with
water.
b. Secure to vertical vent tee with hose clamp or
plastic cable tie.
c. Runcondensatedrainlinetooordrainor
