The Recessed Dryer Vent Box a.k.a. The Dryerbox offers
the architect tremendous value. It provides a UL Through
Penetration Firestop System receptacle in the wall to house
the dryer flex transition hose. This allows both the
washer and dryer appliances to be moved back an extra 4 or
more inches which in turn provides close to two extra square
feet of living area and maybe solving a wall layout problem.
It is simple to specify, available from over 1,900 wholesale
suppliers throughout the United States and will impress your
client with your conscious effort to save them money, space
and provide an innovative idea.
The product is commonly referred to as The Dryerbox by In-O-Vate
Technologies, Inc., under part numbers of DB-425, DB-350,
DB-4D and DB-3D. The 425 refers to our most popular
model measuring 4 1/4" deep (nailing flange to rear of
box). 350 is 3 1/2" deep but exhibits a "squished"
or oval hole (port) to accommodate the squished 4" rigid
pipe. We recommend the DB-425 for upward exhaust direction
and the DB-4D for going down.

 Do
you design the mechanical wall behind the washer dryer with
a 2x4 stud size or a 2x6. Due to the size of the rigid Snaplock
4" vent pipe and the necessity in some regions to provide
a 4" plumbing vent stack, it is advisable and common in
many parts of the US to build that wall behind the washer and
dryer with a 2x6 stud wall. The outside dimensions of both the
metal exhaust Snaplock pipe or the plumbing stack are in excess
of the limited 3 1/2" space a 2x4 provides. |

The Dryerbox provides some interesting advantages.
Besides the many obvious benefits, the receptacle is a sensible
change to the dangerous and inefficient way dryers have been
exhausted for decades. The heavy molded steel construction
appears to exceed code requirements for air distribution components,
and at the same time look very finished. Below are some
letters that may be useful in permit preparation or "red-tag"
challenges. |

Oval hole characteristics with model 350.
Engineer's letter confirms no airflow performance impact with minor change in shape
when pipe is ovalized due to restrictions

Our product is paintable. This letter by the owner
clearly identifies and answers any questions relating
to the paintability of the product.
It also explains the lack of need to mask off the surface
of The Dryerbox, saving time and expense.

 For
stackable washer/dryer units or dryers mounted on
pedestals, The Dryerbox can and should be installed at
the proper location to allow the dryer transition flex
hose to be collected and stored in The Dryerbox
receptacle.

Sec. 504.3 of the ICC Int'l Mech Code/2003 requires a
clean-out at the base of vertical risers
in dryer exhaust systems. Our engineers' professional
opinion is that The Dryerbox meets the requirements as
a clean-out opening for the dryer exhaust system.

Note: The heavy 22 gauge molded steel construction
exhibits similar characteristics of other sheet metal products
common to the HVA/C industry and hence is generally acceptable
by the governing code commissions in the mechanical code section.
In some municipalities, the Dryerbox is code.
Due to the products obvious abilities to reduce the fire hazard
by eliminating the potential of the flex hose from getting
“kinked” or squished, and provide for a more efficient appliance
operation, The Dryerbox is applauded by Building and Mechanical
inspectors. |
