Model HEP
HEP
model High Efficiency Pressure is a single wall stainless
steel chimney. This chimney is UL listed for positive pressure applications
up to 60" water column.
Features
- Wall: AL29-4C (26ga - 6" (152mm) to 12" (305mm) diameter;
24ga - 12" (305mm) to 48" (1219mm) diameter)
- Continuous plasma-weld
- Full range of accessories including elbows, fittings, guides and supports.
Applications
- Models HEP, HEPL and HEPL2
venting systems are primarily intended to be installed in fire resistive,
non combustible surroundings or in unenclosed installation. They are
not intended for use in one or two-family dwellings. (CAUTION: Do not
enclose this venting system in chase or passageway made of wood or other
combustible material.)
- Where the venting system extends through any zone of a building outside
the area in which the heating appliance connected to it is located,
it shall be provided with an enclosure having a fire resistance rating
equal to or greater than the fire rating of the floor, wall or roof
assemblies through which it passes.
- Models HEP, HEPL and HEPL2
venting systems may penetrate a combustible roof or wall using the Ventilated
Roof Flashing assembly. For wall penetrations, the use of the Wall Firestop
assembly is required. This is the only part intended for use with combustible
construction. All other parts, such as Anchor Plate and Wall Support,
Wall Guide and Floor Guide are for attachment to non-combustible construction.
- Where, according to local code, no chase enclosure is necessary, models
HEP, HEPL and HEPL2
may be placed adjacent to or on each pipe section and in the individual
listing; see "CLEARANCES". Contact local building or fire
officials about restrictions and installation inspection in your area.
Listings
CHEMINEE LINING.E inc. venting systems models HEP,

Sample Specification (Boiler Exhaust)
The chimney and flue must meet UL (Underwriters Laboratories inc.) and
c-UL (Underwriters Laboratories of Canada Inc.) standards and carry the
appropriate approval labels. The maximum temperature must be 550°F
(288°C) for continuous operation.
The chimney and flue components must be of double wall construction and
properly designed for positive pressure exhaust. The inner wall must be
of 24 gauge AL29-4C stainless steel, with continuous plasma welds. The
outer wall must be of 24 gauge 304 stainless steel. A high temperature
insulation (2 in.) must be installed between walls. The jointing must
be made using the assembly band, the finishing band and the appropriate
sealing material, as supplied by the manufacturer. Quality required: Model
HEPL2.
All components must be installed according to the manufacturer recommendations
and must meet the NFPA and local safety code requirements.
