Air intake piping: Warning - Risk of damage to appliance. Ensure rain water is prevented from
entering.
Free flow of condensate from venting systems and the pressure vessel must be maintained at all
times. Trap and condensate drain piping must be accessible to allow regular inspection and cleaning.
Condensate water line: Warning - Risk of damage to appliance. All condensate discharge lines,
including neutralization tank inlet, must be at a lower elevation than the condensate water line of the
appliance.
Condensate neutralizer: Drain materials subject to corrosion must be protected by acid neutralization.
Warning - Risk of injury. Tank fluid can be highly acidic. Do not use hands to stir material. Refer to the
neutralization instructions of the manufacturer. Access to the discharge, before the drain, is necessary
for proper maintenance in order to check the effectiveness of the neutralizing agent. A simple pH test
should be performed annually to ensure neutralizing agent is still effective. If the pH falls below 6.5
the neutralizing material should be replaced. The agent (limestone chips with a minimum calcium
carbonate content of 85%) can be purchased from a local supplier.
1" FPT inlet and outlet. Unions for ease of maintenance (ships with shown model NT-25, IBC part 180-
048).
To drain. Confirm slope. Slope the condensate hose and drain piping toward the drain and secure to
prevent accidental dis-assembly.
