3. Minimum vent length is 18" (46 cm) when 4" pipe is used and 45'
(13.7 m) when 6" pipe is used.
CEMENTING PVC OR CPVC PIPE AND FITTINGS
Read and observe all safety information printed on primer, cleaner,
and cement containers.
PRIMER, CLEANER, AND CEMENTS ARE EXTREMELY FLAMMABLE.
THEY ARE HARMFUL OR FATAL IF SWALLOWED. THE VAPORS
ARE HARMFUL. THEY MAY IRRITATE EYES AND SKIN AND CAN BE
ABSORBED THROUGH THE SKIN.
ALWAYS STORE PRIMERS, CLEANER, AND CEMENTS IN
COOL, DRY, WELL VENTILATED PLACES. DO NOT STORE
THEM NEAR HEAT, SPARKS, OR FLAMES. KEEP CONTAINERS
CLOSED. USE THEM IN WELL VENTILATED AREAS. WEAR
IMPERVIOUS CLOTHING WHILE HANDLING. DO NOT SMOKE,
EAT, OR DRINK WHILE HANDLING. WASH THOROUGHLY
AFTER HANDLING AND BEFORE EATING. WEAR EYE
PROTECTION WHEN HANDLING. IF SWALLOWED, DRINK
WATER, DO NOT INDUCE VOMITING, AND CALL A PHYSICIAN
OR POISON CONTROL CENTER IMMEDIATELY. IF INHALED,
GET FRESH AIR AND SEEK MEDICAL ATTENTION IF ILL
FEELINGS PERSIST. IN CASE OF EYE AND SKIN CONTACT,
IMMEDIATELY FLUSH WITH PLENTY OF WATER FOR 15
MINUTES AND SEEK MEDICAL ATTENTION IF IRRITATION
PERSISTS. KEEP OUT OF REACH OF CHILDREN.
All primers, cleaners, and cements must meet all local codes and applicable
standards of the American Society For Testing Materials Standards.
Before using primers, cleaners, and cements, stir or shake, making sure
contents are liquid. Do not use if found to be lumpy or jellylike.
1. Cut pipe ends squarely removing all burrs and dirt.
2. Dry fit pipe and fittings to be connected for proper fit.
3. Clean pipe and fitting with a primer/cleaner.
4. Apply a thin coat of cement to fitting, avoiding puddling inside.
5. Apply a liberal coat of cement to pipe leaving no voids.
DANGER
CAUTION
6. QUICKLY assemble parts while cement is fluid! If you wait too long,
recoat pipes.
7. Push pipe completely into socket of fitting, turning as it goes until it
bottoms.
8. Hold pipe and fitting together for 30 seconds. Then carefully clean off
excess with a cloth. Allow connections a sufficient time to cure before
disturbing.
9. Remember that vent pipes must be adequately and securely
supported.
APPROXIMATE SETTING TIME FOR 2 1/2" TO 6" PIPE JOINTS
90°F to 150°F
50°F to 90°F
0°F to 50°F
VENT PIPE SEPARATION
The inlet and outlet vent pipes must be separated by a minimum distance of
10 1/2" (27 cm) with 4" vent, 12" (30.5 cm) with 6" vent and up to 24"
maximum.
NOTE: Inlet and outlet vent pipes from multiple power direct vent
water heaters must be separated from adjacent heater vent pipes
by a minimum of 10 1/2" (27 cm) with 4" vent or 12" (30.5 cm) with
6" vent.
CUTTING OPENING THROUGH AN OUTSIDE WALL AND COLLAR
INSTALLATION
After reading the manual and you have determined the location of the
opening in the wall, (using the drawing below), cut one 4 1/2" (11 cm)
diameter (for 4" vent pipe) or 6 1/2" (16.5 cm) diameter (for 6" vent pipe)
hole for the inlet vent piping and one 6 1/2" (16.5 cm) diameter (for 4" vent
pipe) or 8 1/2" (21.6 cm) diameter (for 6" vent pipe) hole for the outlet vent
piping through an exterior wall.
NOTE: When determining location of the openings in the outside
wall allow for the 1/8" (3 mm) rise per 5' (1.5 m) that has taken
place in the horizontal run.
