GTS HUMIDIFIER LX SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
INSTALLATION
Flue gas condensate
Piping:
FLUE CONDENSATE PIPING GUIDELINES
• Follow local code requirements for discharge of condensate. The flue gas
condensate will have a 2-4 pH range and may need to be treated prior to
discharge.
• Minimum drain pipe size is
5/8
" inside diameter.
• If treatment is needed, DriSteem offers a condensate neutralizer kit.
The neutralizer should be installed per manufacturer instructions below
condensate p-trap level. Avoid obstructions as condensate could be
damaging to surrounding surfaces and articles.
• Prime the condensate p-trap at the base of the secondary heat exchanger.

Notes:
1. Use flexible tubing that is rated for acidic condensate.
2. All tubing must allow flow away for humidifier to condensate
neutralizer (if equipped).
3. Condensate neutralizer should be installed per manufacturer
instructions below the condensate p-trap level.
4. If floor drain is greater than 5' (1.5 m) from humidifier, use a
5/8" PVC pipe instead of a hose.
