1) (Q) When and where are sediment traps required?
(A) Section 408 requires a sediment trap as close as practical to the inlet side of the equipment. This would include gas regulators. Regulators for individual appliances may utilize a single trap for both the regulator as well as the appliance. Illuminating appliances, ranges, clothes dryers, gas logs, log lighters and outdoor grills are exempt from traps.
2) (Q) May a flexible gas connector run through the appliance housing?
(A) No! Per section 411.1.3.3
1)
(Q) I am terminating a direct vent appliance on the exterior wall of a residential
building. The fireplace I am venting is on the same wall as the porch. The porch
is open on three sides and the termination cap provides adequate protection for
the vent opening. Am I allowed to install this per code?
(A) Yes. A venting system shall be designed and constructed so as to
develop a positive flow adequate to convey flue or vent gases to the outdoor
atmosphere. Once a deck is completely covered and/or screened in, it now
could be an occupied space and would no longer be considered outdoors. We
have to depend on the field Inspector to make an informed judgment. There
are special circumstances where this would be allowed. If the
manufacturer’s instructions allow the installation on an open porch (3 sides)
and the termination vent is protected the installation may be allowed.
