Consumer Products; Granting of the

Application for Interim Waiver and

Publishing of the Petition for Waiver of

Furnace Test Procedures From The

Trane Company (Case No. F-040)

AGENCY: Office of Conservation and

Renewable Energy, Department of

Energy.

BUMMlARY: Today's notice publishes a

letter granting an Interim Waiver to The

Trane Company (Trane) from the

existing Department of Energy (DOE)

test procedures for furnaces regarding

blower time delay for the company's

TUD-C. TUD-R. TDD-C and TDD-R

central furnaces.

Today's notice also publishes a

"Petition for Waiver" from Trane.

Trane's Petition for Waiver requests

DOE test procedures relating to the

blower time delay specification. Trane

seeks to test using a blower delay time

of 45 seconds for its TUD-C, TDD-R,

TDD-C and TDD-R central furnaces

instead of the specified 1.5-minute delay

between burner on-time and blower ontime. DOE is soliciting comments, data,

and information respecting the Petition

for Waiver.

DATE: DOE will accept comments, data,

and information not later than February

10,1992.

ADDRESSES: Written comments and

statements shall be sent to: Department

Gentlemen: This is a Petition for Waiver

'temperature. using the thermocouple grid - -:

described above, at 0.5 and 2.5 -minutes after

the main burner(s) comes on. After the burner

start-up, delay the blower start-up by 1.5

minutes (t-). unless: (1) The furnace employs

a single motor to drive the power burner and

the indoor air circulation blower, in which

case the burner and blower shall bestarted

together, or (2'i the furnace is designed-to

operate using an unvarying delay time that is

other than 1.5 minutes, in which case the fan

control shall be permitted to start the blower,

or (3) the delay time results In the activation

of a temperature safety device which shuts

off the burner, in which case the fan control

shall be permitted to start the blower. In the

latter case, if the fan control is adjustable, set

it to start the blower at the highest .

:temperature. If the fan control is permitted to

start the blower, measure time delay. (t-),

using a stop watch. Record the measured

temperatures. During the heat-tip test for oilfueled furnaces, maintain the draft in the flue

pipe within ±0.01 inch of water column of

the manufacturer's recommended on-period

draft.. .

This Interim Waiver is based upon the

presumed validity of statements and all

allegations submitted by the company. This

Interim Waiver may be revoked or modified

at any time upon a determination that the

factual basis underlying the application is

incorrect., _ , ..

The Interim Waiver shall remain in effect .

minute delay between burner and supply air

blower startup. Trane is requesting the use of -

i5 seconds instead of 1.5 minutes when

testing our TUD-C, TDD-R. TDD-C and

TDD-R central furnace families incorporating

a timed fan control with a fixed timed on -

adjustment of 45 seconds. The current

procedure does not credit Trane for

additional energy savings that are realized

when a shorter blower on time is utilized.

Test data for each model series indicates an

average 1% AFUE increase when a 45 second

timed on delay is used. Copies of confidential

test data confirming these energy savings will

be forwarded to you upon request.

Trane is confident that this petition for

Waiver will be granted, and therefore,'

requests an interim Waiver until the final

ruling is made. Similar waivers have been

granted to Evcon, Rheem Manufacturing,

Carrier, Inter-City Products, and Lennox

Industries. Also, the proposed ASHRAE 103-

8e currently under consideration by DOE

contains the coverage requested in this

Petition for Waiver.

Manufacturers that domestically market

similar products have been sent a copy of this

Petition for Waiver and Application for

Interim Waiver. •- •
