Condensate Drains:
When An Internal Condensate Drain Is NOT Part of the Appliance:
• A Saf-T Vent SC In-Line Drain Section is strongly recommended. Install this drain fitting as close to
the appliance flue collar as possible.
• A condensate drain is required for every 30 feet of horizontal vent and at/near the bottom of a
vertical stack.
• Use the In-Line Drain Section for a straight horizontal or vertical run. When used horizontally, rotate the
fitting so that the drain tube is as vertical as possible.
• A Condensate Drain Tube Kit is available to direct the condensate to an appropriate location, i.e. floor
drain or vented sanitary sewer connection. A trap loop must be formed into the drain hose and must be a
diameter that is at least four times the appliance's rated stack pressure in inches of water column or 3
inches, whichever is greater. Secure the loop with a cable tie. Prior to final assembly the trap loop must
be 'primed' by pouring a small quantity of water into the drain hose. Inspect at least annually to verify the
trap is 'primed'.
• Follow all local and national codes and regulations for the draining of acidic condensate.
• In cold climates do not install a condensate drain on the exterior of the building. Doing so may result in
dangerous icy conditions on surfaces near the drain and may cause damage to the vent system and/ or
the building exterior. Heat-fab, Inc. will NOT be held liable for any injury or property damage due to
formation of ice.
