Canadian Plumbing Code - AmendmentHot Water
Temperature

• 2.10.7 Maximum Temperature of Hot Water
• (1) Except as provided in Sentence (2), the
  maximum temperature of hot water supplied by
  fittings to fixtures in residential occupancy
  shall not exceed 49ºC.
• (2) Sentence (1) does not apply to hot water
  supplied to installed dishwashers or clothes
  washers.

Canadian Plumbing Code - AmendmentHot Water
Temperature

• How to comply
• Fit a master thermostatic mixing valve at the
  water heater to distribute at 49ºC throughout the
  whole house, or
• Fit a mixing valve at each outlet.
• Note Recommend always fit an automatic
  compensating shower valve at each shower fixture.

Principle of Operation

• Designed to mix hot/cold water supplies and
  deliver water at a safe temperature.
• Controlled by an integrated thermostatic element
  that senses the inlet water temperature and adds
  cold water accordingly.
• Heatguard valves also offer a shutdown in case
  of cold water failure.

18
Applications

• Distribution (HG 110, 115) Allows water to be
  stored at a sterilizing temperature and delivered
  at a safe temperature.
• Point-Of-Use (HG 145, 160) Can be used in either
  large distribution systems or directly at the
  hand lavatory, bath, or other direct fixture.

19
Markets

• Heating Accurate, inexpensive valves for
  hydronic heating. High flow rates, low pressure
  loss, wide temperature range.
• Domestic/Potable Water Aid in the prevention of
  scalding and Legionnaires Disease. Heatguard
  TMVs distribute safe, tempered water to the
  outlet while providing washing machines and
  dishwashers with water at a higher temperature.

20
Valve Location

• The most common installation site is directly at
  the water heater.
• - less costly, protects entire system, easily
  serviced
• A valve may also be installed directly at the
  fixture, namely the HG 145 and 160 TMVs.
• - may be best solution to protecting individual
  fixtures
• Installation must follow local codes and
  requirements.

21
Valve Location Direct Installation
22
Valve Location Single Fixture
23
Servicing

• Valve function can easily be checked by measuring
  the water temperature at the outlet nearest to
  the valve.
• - If the temperature is the same as originally
  commissioned, the valve is working fine
• - If the temperature is different, it may
  be because of debris buildup. Disassemble and
  clean the valve.

24
Cash Acme Recommendation

• The installation of a Cash Acme Thermostatic
  Mixing Valve should comply with the local Codes,
  Standards, and Safe Practices.
• Our valves are certified under the applicable
  Industry Standards, and meet or exceed
  performance guidelines.
