Ps. As the furnace condensation line and the furnace itself will now
actually function, CCL should conduct a quick check of (pour maybe 5 gal of
water down?) the floor drain in the small NW room where the condensation
line terminates, and verify the function of the sump pump if it is still
there (and connected to power?), in order to ensure this drain has not
possibly become blocked during its recent tenure of disuse. If it has
become blocked, CCL should contact Albion plumbing or some equivalent
outfit specializing in drain clearing. I would prefer if CCL undertook this
diagnostic work when it can (given the rainy season is also approaching)
and report back the results if possible?
Merci,

Hi,
As of today, mechanical maintenance on the furnace and space heater in CCL
/ Sudo has completed.
The remaining task relating to the furnace specifically is more thoroughly
assessing (and potentially improving) the structural integrity of the
furnace’s platform — potential impacts / schedule of which is TBD.
The following tasks completed:
*A. Furnace in CCL/Sudo* (serving disco Rm):
- replacement of blower motor & fuse,
- installation of unit-adjacent service receptacles,
- installation & test of water pump for condensation line,
- replacement of existing air filter with a finer MERV-13-style
(equivalent HD-branded version) filter. Note this filter will need to be
periodically replaced on a going basis, interval of which is unknown but is
dependent on the frequency of use of this heater and is not anticipated to
be overly frequent.
- successful test activation of furnace / thermostat. We confirmed the
thermostat allows the fan to kick on without the heat if that is desired
(to just filter air).
*B. Space heater in CCL/Sudo* (serving same):
- Successful test / activation,
- Moving its on/off switch from high up in CCL’s BSL over to an accessible
height in common area near north entry to CCL / Sudo,
- Replacement of on/off switch with a 1-hr timer switch (thanks to jake
for supplying this fixture)
Note: the feasibility of potentially macgyver’ing a MERV-13 air filter
onto the space heater (which has no built-in facility for an air filter)
was assessed, but determined to be too much of an unknown safety-wise and
there is no plan to do this at this time.
*C. For both heaters*:
- Basic Installation of off-the-shelf smoke/CO and natural gas/CO alarms
in a reachable area above and roughly between the furnace and space heater.
Ideally these would be placed on the ceiling, but it was determined that
the ceiling was not safe to reach without a taller ladder or scaffolding.
(If CCL or Sudo desires this, let me know.)
These alarm units should not be considered sufficient for today’s code
standards for a commercial space. They are in effect ad-hoc and are
intended mainly as being much better than nothing, as was previously the
case. By comparison, a ‘one-go, all-go’ monitored, interconnected wireless
alarm system (with far more modules) would be the preferred install for
this room and the building.
The present alarm install should be seen as a stopgap until community
funds are provided to achieve a more standard and expansive commercial
detection and notification system in this room and throughout omni.
*There will be three distinct alarm patterns for smoke, CO, or natural
gas. Please read / redistribute / make an meeting agenda item for
identifying the below patterns: *
*Gas/CO detector - Natural Gas detected*:
1/2-second beep, 1/2-second silence, repeating. On A/C power this repeats
indefinitely.
During a power outage (on battery power), it it repeats for the first four
minutes then changed to every 60 seconds to conserve battery.
*Gas/CO detector - CO (carbon monoxide) detected*:
4 quick beeps followed by 5 seconds of silence, repeating.
During a power outage, (on battery power), it it repeats for the first
four minutes then changed to every 60 seconds to conserve battery.
*Gas/CO detector: - Both Natural gas & CO detected*: Alarm priority in
this unit is for CO. If both are detected, it will only alarm for CO.
*Smoke/CO detector - Smoke detected*:
Should be 3 long beeps, repeating.
*Smoke/CO detector - CO detected*:
Should be 4 quick beeps, then a pause, repeating.
Note the gas/co detector is fed by A/C but has a 9V battery backup in
event of power outage — If an extended power outage occurs or eventually
the 9V will die and the unit will chirp annoyingly until the 9V is
replaced. Whereas the smoke/co detector is not wired to A/C, and has an
integrated 10-year lithium ion battery, so it is not impacted by power
outages and should take a decade to start the ‘replace me’ chirp.
To hush either of these alarms in the event a false positive,
unfortunately requires physical proximity, ie a ladder up to the furnace
platform.
Thank you to community members Dave A., Theresa H., Patrik, Michael and
Sarah for assisting this process.
Best,
David
