check the belt tension. I
should have `,4" to 1/2" pla
mid -way between the p}rlleys
If the tension isn't right
loosen the adjusting screw
holding the motor frame to
the motor housing. Slide th
motor until the tension i
right. Tighten the screws —
and check to be sure yo
didn't disturb the alignmen
of the two pulleys.
To increase the flow o
warm air through the house
increase the fan speed by
adjusting the variable
diameter pulley on the motor.
Change the filters. Usually
they're at the back of the
furnace, behind a panel.
Inspect them at least once a
month. If they are dirty,
replace the disposable
fiberglas type or wash out the
semi-permanent type. (You
might try vacuuming the
disposable type and using
them again.) Dirty filters
block the circulation of air,
reduce the furnace's ef-
ficiency and cost you money.
You'll find disposable
filters in your hardware or
department store. The sizes
are marked, such as 16 x 20 x
1". The filters fit on ledges
behind the back door of your
furnace and installing the
right size is important. Some
of the semi-permanent ones
can be cut to size and washed
out once a month. (But do it in
cold water, please!)
If you don't need extra
heating in your basement, all
the exposed ducting should be
taped at each joint and in-
sulated with Fiberglas or
mineral -wool insulation.
(Warning: Never use foamed
plastic insulation because it's
a fire hazard.)
A warm -air register can be
accidentally blocked by
simply dropping a newspaper
on- it. The warm air that
should be coming into the
room will go elsewhere, and
your furnace will have to
work overtime. If the
registers are under a window
and you happen to close the
curtains or drapes in front of
them, the warm air merely
heats the window. What a
waste! So be sure to keep
registers clear of such heat -
robbers as curtains, drapes,
furniture and carpeting.
Almost any hardware store
will have plastic deflectors
for hot-air registers. They
shoot the heat away from the
cooler outside walls and into
the main living area.
Hot-water heating is the
most common alternative to
warm air. Water is pumped
through tubes in the furnace
and heated to a maximum of
180 degrees F (82 degrees C),
then circulated through the
house in pipes. After giving
up heat to the radiators, the
cooled water returns to the
pump and starts the cycle all
over again.
The system always has an
expansion tank and pressure
relief valve to prevent ex-
cessive pressure build-up. A
flow -control valve stops the
water when the circulating
pump is notworking.
The expansion tank has an
automatic water feed. Relief
valves should be checked and
the water drained off to
provide an air space for
expansion of the heated
water. Different systems use
slightly different methods to
restore the air cushion in the
tank, so look in your owner's
manual for these instructions
and the location of drain taps.
Hot-water pipes going to
and from radiators should be
well insulated, especially in
areas that don't need heat.
To run efficiently, the
system needs water in all
radiators and in the boiler.
e Each fall, before start-up,
check your water -level gauge
on the boiler.
In the fall, when your
t system goes on for the first
time, bleed the air from each
f radiator. If you don't, air will
stop the water flow and the
radiators will stay cold. Open
the vent screw at one end of
the radiator and keep it open
until hot water spurts out —
into a handy cup or glass.
You'll need a screwdriver or
small wrench to open the
vent, and when you're
finished, be sure the water
isn't dripping.
Wipe away dust and dirt to
let more heat out. Don't set
bookshelves, chairs or drapes
directly in front or on top
because they also slow up the
heat flow. Let the heat out at
both top and bottom.
Stay away from metallic
paints and glossy light colors.
Use a matte or satin finish.
A sheet of aluminum foil
against the wall, behind the
radiator, will direct the heat
into the room.
Steam heating is found
mainly in older homes and is
similar to the hot-water
system, but uses steam at 212
degrees F (100 degrees C).
Water is heated to boiling in a
boiler, and the steam rises
through pipes to radiators in
each room of the house. Here
Special
house
built
A house in
Penetanguishene, built in
collaboration between
Ontario Hydro and Viceroy
Homes of Toronto, serves as a
pilot project for what might
be called "super insulation".
It was engineered and built
by Viceroy to demonstrate
that super insulation can
become routine in average
houses at no extra cost. It has
been hailed by Hal. K.
Wright, director of Ontario
Hydro, as "an outstanding
achievement in energy
conservation."
There are three basic in-
novations, all of them major
departures from conventional
building techniques in win-
dow, wall and roof con-
struction.
- Every window in the house
is triple sealed with two air
spaces between three panes
of glass. Tests by the Ontario
Research Foundation show
the heat loss is 40 per cent less
than with conventional double
glazed windows.
The exterior walls of the
house are framed with two by
six studs as compared to the
four inches which is the
minimum recomMended by
Ontario Hydro.
The R -factor, or thermal
resistance, is raised from R-
12 to R-20.
Besides, the external
strength of the walls is in-
creased 30 per cent by using
heavier studding, but the cost
is about the same because
fewer studs are used.
In the ceilings, the com-
pany has placed eight inches
of insulation with a factor of
the Steam is condensed to
water, releases heat to the
room, and returns to the
boiler by gravity.
Water in the boiler should
be kept at the level recom-
mended by your manufac-
turer. Check the glass gauge
usually found on the boiler. If
there isn't enough water in
the system, the heating unit
will shut off; too much water
will reduce the boiler's ef-
ficiency. Once a month
through the heating season,
flush out and clean the boiler.
Open the "flushing" valve
(find it with the help of your
instruction manual) and
drain the water until it runs
clear. Then refill the boiler to
its proper level.
If you have leaky joints,
both steam and heat will
escape. Repair them yourself
or call a plumber.
