Multi--venting and Vent Terminations
When 2 or more 58MVC Furnaces are vented near each other, each
furnace must be individually vented. NEVER common vent or
breach vent 58MVC furnaces.

CONDENSATE DRAIN
General
Condensate trap is shipped installed in the blower shelf and factory
connected for UPFLOW applications. Condensate trap must be
RELOCATED for use in DOWNFLOW and HORIZONTAL
applications.
Condensate trap MUST be used for all applications.
An external trap is not required when connecting the field drain to
this condensate trap.
The field drain connection (condensate trap or drain tube coupling)
is sized for 1/2--in. CPVC, 1/2--in. PVC, or 5/8--in. ID tube
connection.
Drain pipe and fittings must conform to ANSI standards and
ASTM D1785, D2466, or D2846. CPVC or PVC cement must
conform to ASTM D2564 or F493. Primer must conform to
ASTM F656. In Canada, use CSA or ULC certified schedule 40
CPVC or PVC drain pipe, fittings, and cement.
When a condensate pump is required, select a pump which is
approved for condensing furnace applications. To avoid
condensate spillage, select a pump with an overflow switch.
Furnace condensate is mildly acidic, typically in the pH range of
3.2 to 4.5. Due to corrosive nature of this condensate, a condensate
pH neutralizing filter may be desired. Check with local authorities
to determine if a pH neutralizer is required.
Application
The furnace, A/C, and humidifier drains may be combined and
drained together. The A/C drain must have an external,
field--supplied trap prior to the furnace drain connection. All drain
connections (furnace, A/C, or humidifier) must be terminated into
an open or vented drain as close to the respective equipment as
possible to to prevent siphoning of the equipment’s drain.

See Fig. 45 for example of possible field drain attachment using
1/2--in. CPVC or PVC tee for vent and A/C or humidifier drain
connection.
Outdoor draining of the furnace is permissible if allowed by local
codes. Caution should be taken when freezing ambient may freeze
drain pipe and prohibit draining.
PERSONAL INJURY HAZARD
Failure to follow this warning could result in personal
injury or death.
Caution should be taken to prevent draining where slippery
conditions may cause personal injuries. Excessive
condensate draining may cause saturated soil conditions
which may result in damage to plants.

WARNING
Condensate Drain Protection
Freezing condensate left in condensate trap and drain line may
cause cracks, and possible water damage may occur. If freeze
protection is required, use condensate freeze protection accessory
or equivalent 3 to 6 watt per ft. (.3M) at 120v and 40
